High temperatures and pressures are given for the following power plants.
ISU co-generation: 400 psi, 750F
City of Ames with RDF: 700 psi, 850F
Super-critical power plant 3500 psi, 1100F
Assuming a low temperature of 75F, find the maximum possible efficiency of each of these 3 cycles.
Assumptions: Kinetic Energy=KE, Potential Energy=PE m=mass of the skateboarder=55 kg, Velocity v=1.80m/s So ,Initial Energy(KE) of the skateboarder=mv 2 /2 = 0.5* 55 * (1.8)^
Resistivity of conductors is most affected by (A) Composition. (B) Temperature. (C) Pressure. (D) Current. Ans: Resistivity of conductors is most
what is the motion of an oscillating column in a u-tube?
Q. What is efficiency of a transformer? Efficiency of a transformer is described as the ratio of output power to the input power. η= output power / input power
Is it possible to see your whole body in a flat, planar mirror that is LESS THAN half your height if the mirror is at an angle? (i.e. not parallel to your body)
Photons and gravity : It is observed that light is affected by gravity. We can recognize the gravitational behaviour of light from the fact that although a photon has zero rest mas
Using a pulley Use the pulley set-up shown in experiment A 12. Apply the force on the movable pulley and get how rapidly the weight on the other end of the string rises.
a dock worker loading crates on a ship finds that a 24kg crate, intially at rest requires a 65N horizontal force to set it in motion.However,after the crate is in motion, a horizon
An experiment with force and motion Tie a spring clothes peg open by placing one winding of thread about the long ends. Place the clothes peg in the centre of a long table and
Sound waves are being used to determine the depth of a freshwater lake, as shown in the figure below. If the water is 25°C and it takes 1.2 s for the echo to return to the sens
