Air expands through a turbine operating at steady state on an instrumented test stand. At the inlet p1 = 160 lbf/in2, T1 = 1560oR. And at the exit, p2 = 14.8 lbf/in2. The mass flow rate of air entering the turbine is 10.5 lbm/s, and the power developed is measured as 2550 horsepower. Neglecting the heat transfer, KE and PE changes, find exit temperature

A small hydroelectric power plant produces electrical power at a rate of 30 kW. The plant utilizes a stream of water that drops 40 m from a lake to the turbine and flows at a rate of 100 kg/s. What is the efficiency of the turbine-generator?
Calculate the force required in direct extrusion of 1100-O aluminum from a diameter of 6 in. to 2 in. Assume that the redundant work is 30% of the ideal work of deformation, and the friction work is 25% of the total work of deformation.
(a) derive an expression for the net work transfer for the cycle. Prove that for a Stirling Cycle, the net work transfer is always from the system to the surroundings.
What is the nature of the process fluid and what are the objectives of the two sample points and in what way do the samples reaching the instruments differ?
In the gear-and-shaft system shown, the shaft diameters are dab= 2 in. and dcd=1.5 in. Knowing that G = 11.2 x10^6 psi, determine the angle through which end d of shaft cd rotates.
