: Assume the turbine is ideal and adiabatic. What is the specific entropy of the steam as it exits the turbine and enters the condenser? Hint: you need to use the results from the previous problem. View
: Consider a Rankine power plant that has uses no reheat with water as the working fluid. The steam generator operates at 100 bar and the condenser operates at 10 bar (absolute). The water enters the turbine at a temperature of 775 degrees Celsius. Assume no losses in the system. What is the specific enthalpy and the specific entropy of the water as it enters the turbine? View
: The Brayton cycle has the same 4 processes as the Rankine cycle, but the T-S and P-V diagrams look very different; why is that? View
: *COP > 1…. If the heat transfer into a refrigeration system is 278 kJ/s and the work of the cycle is 325 kJ/s, then what is the efficiency of the refrigeration system? View
: What is the mass flow rate of a refrigeration fluid with a density of 1136 kg/m^3, a volume flow rate of 0.015 cm^3 / s? View
