Volume resistance: The resistance provided to the current which flows through the material is called volume resistance. For a cube of unit dimensions this is called volume resistivity. This resistivity is the flow of current resistance offered to the flow of current through the body of the material, and is expressed in the same way as the resistivity of a conducting material. In ohm-m. Thus the volume resistance of an insulating material may be expressed as
R=ρvd/a
Where ρV IS called the volume resistivity, and is expressed in terms of ohm-m. "d" is length of the current path through the material in meters, "a" is the cross section area on the current path in square-m.
Surface resistance: The resistance offered by to current I which flows over the surface of insulating material is called surface material. Surface resistivity depends upon the humidity.
A mass flow of 10kg/s of water vapor at 30bar and 500 0 C flows steadily through the inlet an insulated turbine. The pressure of the water is reduced to 1bar at the turbi
a jet of engine on a test tube takes in 20kg of air per second at a velocity of 100m/s and burns 0.8kg of fuel per second.after compression and heating the exhaut gases are ejected
After the parallel algorithm has been written as well as executed performance of both algorithms is one of other main concerns. In order to examine performance of algorithms there
Gauss' law of magnetism, Gauss' law of electricity,Faraday's law of induction, and Amperes' law form the basic equations of electromagnetism. This combination is collectively
Rayleigh-Jeans law For any blackbody at thermodynamic temperature T, the radiancy R onto a range of frequencies among nu & nu + dnu is provided by R = 2 pi nu 2 k T/c 2 .
Centrifugal pseudoforce A pseudoforce which occurs while one is moving in consistent circular motion. One feels a "force" directed outward from the center of motion.
