Use the Rankine cycle. The boiler operates at a 1000 kpa with a maximum temperature of 30 degrees Celsius. The condenser is isobaric and operates at -5 degrees Celsius.
a) calculate the vapor quality leaving the turbine and the specific enthalpy exiting the turbine (in kj/kg).
b) determine the specific-work produced by the rankine cycle turbine (kj/kg), assuming it is ideal and adiabatic.
c) show the cycle on a t-s diagram.
d) determine the specific work required by the rankine cycle pump (in kj/kg), assume it is ideal and adiabatic.
e) determine the specific QH for the rankine cycle (kj/kg).
F) calculate the rankine cycle (thermal) efficiency.
g) Compare the required material strength and cycle efficiency of this rankine cycle with a carnot cycle operating with the same TH (30 degrees celsius) and TL is (-5 degrees celsius) by calculating the percent change in max pressure and thermal efficiencies.
