       If light want to escape form Black Hole  he can't escape Why??. The answer is that any gas or dust near the black hole tends to pulled into an accreditation disk that swirls around and into the black hole , rather like a whirlpool    Friction within the accreditation disk material causes it to lose a mechanical energy and spirl into the black hole ; as it is moves inward , it is compressed together . This causes heating of the material , just like as air compressed in a bicycle pump gets hotter.

Black hole            The concept of a black hole is one of the most interesting and startling products modern gravitational theory          In 1783 the Rev.John Mitchell, amateur astronomer , noted that if a body with same average density as the sun had about 500 times the radius of the sun , magnitude of its escape velocity would be greater than the speed of light C . With his statement that "alllight emitted from such body would like be made to return toward it" Michell became the first person to suggest the existence of what we now call it a Black  hole    This above image of black hole will be post resently on NASA Twitter  https://twitter.com/NASA/status/1177417427405148160?s=20

Today college remains closed by Pune district collecter because of the weather forecast.                     Intense rainfall continued in the city on Tuesday night and early on Wednesday morning, following heavy showers post-midnight on Monday. Shivajinagar witnessed 78.3mm rainfall in 12 hours between 8.30pm on Tuesday and 8.30am on Wednesday. The intensity of showers may reduce a bit, but the city is likely to experience thunder and rainfall in the next couple of days, said an official of the  India Meteorological Department  (IMD). According to the IMD’s data, Shivajinagar recorded only 0.4mm rainfall between 8.30am and 5.30pm on Tuesday. There was 8.3mm rain in the next three hours. In the next 12 hours, Shivajinagar recorded 78.6mm rainfall.    That's why college and school will be closed on 27th September 2019   For more information visit this page

Application Considerations With respect to temperature, the magnitude ofthe CTE increases with rising temperature .Thermal expansion of pure metals has been wellc up to their melting points, but datafor engineering alloys at very high temperatures may be limited. In general, CTE values for metals fall between those of ceramics (lower values)apolymers (higher values). Common values for metals and alloys are in the range of 10 to 30 × 10–6/K (5.5 to 16.5 × 10–6/°F). The lowest expansion is found in the iron-nickel alloys such as Invar. Increasing expansion occurs with sili- con, tungsten, titanium, silver, iron, nickel, steel, gold, copper, tin, magnesium, aluminum, zinc, lead, potassium, sodium, and lithium. Low-expansion alloys are materials with di- mensions that do not change appreciably with temperature. Alloys included in this category are various binary iron-nickel alloys and several ter- nary alloys of iron combined with nickel- chromium, nickel-...

THE COEFFICIENT OF LINEAR  thermal expansion (CTE, α, or α1) is a material property that is indicative of the extent to which a mate- rial expands upon heating. Different substances expand by different amounts. Over small tem- perature ranges, the thermal expansion of uni- form linear objects is proportional to tempera- ture change. Thermal expansion finds useful application in bimetallic strips for the construc- tion of thermometers but can generate detrimen- tal internal stress when a structural part is heated and kept at constant length. For a more detailed discussion of thermal expansion including theory and the effect of crystal symmetry, the reader is referred to the CINDAS Data Series on Material Properties, Volumes 1 to 4, Thermal Expansion of Solids (Ref 1). Definitions Most solid materials expand upon heating and contract when cooled. The change in length with temperature for a solid material can be ex- pressed as: (l f – l 0)/l 0 = α1 (Tf – T...

Heat transfer and thermodynamics ◉ Heat: The form of energy that can be transferred from one system to another as a result of temperature difference. ◉ Thermodynamics is concerned with the amount of heat transfer as a system undergoes a process from one equilibrium state to another. ◉ Heat Transfer deals with the determination of the rates of such energy transfers as well as variation of temperature. ◉ The transfer of energy as heat is always from the higher-temperature medium to the lower-temperature one. Heat transfer stops when the two mediums reach the same temperature. ◉ Heat can be transferred in three different modes: conduction, convection, and radiation

Scotch Marine Boiler The Scotch marine tire-tube boiler is especially suited to Seabee needs. Figure shows a portable Scotch marine tire-tube boiler. The portable unit can be moved easily and requires only a minimal amount of foundation work. A completely self-contained unit, its design includes automatic controls, a steel boiler, and burner equipment. These features are a big advantage because no disassembly is required when you must move the boiler into the field for an emergency. The Scotch marine boiler has a two-pass (or more) arrangement of tubes that run horizontally to allow the heat inside the tubes to travel back and forth. It also has an internally fired furnace with a cylindrical combustion chamber. Oil is the primary fuelused to fire the boiler; however, it can also be fired with wood, coal, or gas. A major advantage of the Scotch marine boiler is that it requires less space than a water-tube boiler and can be placed in a room that has a low ceiling. The Scot...

Horizontal Return Tubular Boiler In addition to operating portable boilers such as the Scotch marine and vertical fire-tube boilers, the UT must also be able to operate stationary boilers, both in the plant and in the field. A stationary boiler can be defined as one having a permanent foundation and not easily moved or relocated. A popular type of stationary fire-tube boiler is the horizontal return tubular (HRT) boiler shown in Figure 9-16. The initial cost of the HRT boiler is relatively low, and installing it is not too difficult. The boiler setting can be readily changed to meet different fuel requirements—coal, oil, wood, or gas. Tube replacement is also a comparatively easy task since all tubes in the HRT boiler are the same in size, length, and diameter. The gas flows in the HRT boiler from the firebox to the rear of the boiler. It then returns through the tubes to the front where it is discharged to the breaching and out the stack. The H RT boiler has a pi tch o f...

 Vertical-Tube Boiler In some fire-tube boilers, the tubes run vertically, as  opposed to the horizontal arrangement in the  Scotch boiler. The vertical-tube boiler sits in an upright position . Therefore, the  products of combustion (gases) make a single pass,  traveling straight up through the tubes and out the  stack. The vertical fire-tube boiler is similar to the  horizontal fire-tube boiler in that it is a portable, self- contained unit requiring a minimum of floor space.  Handholes are also provided for cleaning and  repairing. Though self-supporting in its setting (no  brickwork or foundation being necessary), it MUST  be level. The vertical fire-tube boiler has the same  disadvantages as that of the horizontal-tube  design—limited capacity and furnace volume. Before selecting a vertical fire-tube boiler, you must  know how much overhead space is in the building  wh...

Electrical Resistance  Resistance (R)  Any device in a circuit which converts electrical energy into some other form impedes the current. The device which converts electrical energy to heat energy is termed a resistor and its ability to impede current is termed resistance. So resistance can be defined as the opposition to current caused by a resistor.  The value of resistance of a conductor depends upon four things; 1. The material from which the conductor is made, 2 The length of the conductor (in the direction of the current path), 3 The thickness (cross-sectional area of the conductor), 4 The temperature at which it operates (in general, the higher its operating temperature the greater its resistance). Unit of Resistance - Ohm (Ω)  Resistance is measured in ohms (symbol Ω)). All materials at normal room temperature have electrical resistance. If the material is classed as a conductor its resistance is probably much less than 1000 ohms. If the ...

Hola chicos            Soy Prasad y ganamos aprender sobre el CAPACITOR CONDENSADOR           Cualquiera de las dos superficies conductoras separadas por un material aislante (dieléctrico) se llama capacitor. Como vemos en la siguiente figura, hay dos placas y las placas del condensador y el material aislante llamado dieléctrico. El condensador puede estar en forma de placas paralelas, cilindro concéntrico u otra disposición ¿CÓMO SE COBRA LA ALMACENAMIENTO DE CAPACITOR?                   Cuando el interruptor de la batería está encendido y está conectado al condensador, los electrones comienzan a acumularse en las placas del condensador. El resultado es que una de las placas tuvo carga positiva (+) y otra placa tuvo carga negativa (-). Esta acción se conoce como cargar un condensador porque las placas del condensador se cargan APLICACIÓN DEL CAPACITOR.  Son un compon...

Hey Guys           Transformers is the probably one of the most useful electric devices ever invented.  “ TRANSFORMER”- one of oldest innovations in Electrical Engineering. A Transformer is an electrical device that can be used to transfer the power from one circuit and another circuit without physical contact and without changing its characteristics like frequency, phase.   Transformers-how it's work   A transformer is an electrical apparatus designed to convert alternating current from one  voltage to another. It can be designed to "step up" or "step down" voltages and works on  the magnetic induction principle. A transformer has no moving parts and is a completely  static solid state device, which insures, under normal operating conditions, a long and  trouble-free life. It consists, in its simplest form, of two or more coils of insulated wire  wound on a laminated steel core. When voltage is introduced to ...
