energy is added to a piston cylinder arrangement, and the piston is withdrawn in such a way that the quantity PV remains constant. the initial pressure and volume are 200kpa and 2m3, respectively. the final pressure is 100kpa, calculate the work done by the gas on the piston.
Tensile force formulas, A cylindrical steel beam is 2 inches diameter and 6 feet long. The modulus of elasticity is 30 x 1,000,000 psi. If the beam is subjected to a tensile force of 1000 lbs, what will be the resulting unit strain?
Evaluate thermal efficiency of the cycle
Determine the total heat transfer and the total work(kj). and show the T-V diagram.
A ball is thrown vertically up with a velocity of 91 ft/sec at the edge of a 190-ft cliff. Calculate (a) the height h to which the ball rises and (b) the total time t after release for the ball to reach the bottom of the cliff.
Steam at 1000kPa and 300deg C expands to a pressure of 150kPa in a cylinder. If PV = constant during the process, calculate W, Q and delta S for the process.
B) Determine the minimum amount of work [kJ ] required to reach this end state. C) If more than the minimum work is actually used, where does this extra energy go? That is what becomes of the extra energy?
