Water at 366.65K is pumped from a storage tank at the rate of 3.15*10-3m3 s -1 . The motor for the pump supplies work at a rate of 1.5kW. The water goes through a heat exchanger, giving up heat at the rate of 700kW, and is delivered to a second storage tank at an elevation 15m above the first tank. What is the temperature of the water delivered to the second tank?

Air is contained in a piston cylinder arrangement as undergoes a cycle as shown in the figure. The initial temperature T1 = 800oF and the amount of air is 1 lbm. The process from 3 to 1 is adiabatic. Determine the total work and the net heat transfer in Btu. Assume constant heat capacities.

A gas turbine power plant with the following specifications: two axial compressor stages, the pressure ratio is 6/1 for each compressor. The inlet and exit angles of both moving and fixed blades are 40° and 20° respectively, the work done factor is 0.82, six stages for each compressor. intercooling between stages. A high pressure turbine is used to drive the compressors, and a low pressure turbine drives the generator. The temperature of the gases at entry to the high pressure turbine is 600°C and the gases are reheated to 700°C after expansion in the first turbine. The exhaust gases leaving the low pressure turbine are passed through a heat exchanger to heat the air leaving the high pressure stage compressor. The air inlet temperature to the unit is 20°C. The isentropic efficiency of each turbine stage is 0.95; the heat exchanger thermal ratio is 0.7. A mechanical loss is 5% for both the generator- turbine shaft and the compressor- turbine shaft. Assume any missed values to Calculate…
