Question
(a) the rates of entropy production (kW/K) for the turbine, condenser, and pump
(b) using part (a), rank the components in order, beginning with the component contributing most to inefficient operation of the overall system, and
(c) sketch the cycle on a T-s diagram.
The figure shows a vapor power plant operating at steady state with water as the working fluid. The mass flow rate of the water circulating through the components is 100 kg/s. Determine: the rates of entropy production (kW/K) for the turbine, condenser, and pump using part (a), rank the components in order, beginning with the component contributing most to inefficient operation of the overall system, and sketch the cycle on a T-s diagram.Explanation / Answer
the work done is
W = P x V
where P is pressure and V is volume
let T be the final temperature
the change in entropy is
dS = (W/T)
the power is
P = (W/t)
where t is time
