In a steady-state operating power plant, saturated liquid H2O at 122 deg C is fed to a boiler at 3.756 m/s through a pipe (0.03 m diameter). It leaves the boiler at 9 bar and 88.7 m/s. Then, it enters the turbine through a constant 0.13 m diameter pipe. The exit pipe of the turbine is 0.3 m in diameter and T = 310ºC while P = 1.37 bar. If 2.5 kg/s water is fed and there is change in KE, prove that the fluid enters the turbine at 637.06 deg C.
3. In a gas turbine plant air is compressed from 1.01 bar and 15 °C through a pressure ratio of 5. It is then heated in a combustion chamber at constant pressure to a temperature of 700 °C and expanded to atmospheric pressure in a turbine. The isentropic efficiencies of compression and expansion are respectively 0.8 and 0.85. Calculate (a) the cycle efficiency and (b) the work ratio. Assume that the properties of air do not change with temperature and may be taken as Cp = 1.005 kJ/kg K and y = 1.4.

A Carnot refrigeration cycle is used as a reference to estimate the energy needed in an attempt to reduce the temperature of a laboratory sample to absolute zero. Suppose you want to remove 0.01 J of energy from the sample that is at 2x10-6K. If the high temperature is 20°C, the heat required is 982.05x10-5J. Analyzing these considerations, calculate the increase in laboratory entropy and the decrease in entropy in the sample.
