Consider a simple ideal Rankine cycle with fixed turbine inlet temperature and condenser pressure. What is the effect of increasing the boiler pressure on:_______.
Pump work input: (a) increase (b) decrease (c) remains the same
Turbine work output: (a) increase (b) decrease (c) remains the same
Heat supplied: (a) increase (b) decrease (c) remains the same
Heat rejected: (a) increase (b) decrease (c) remains the same
Cycle efficiency: (a) increase (b) decrease (c) remains the same
Moisture content at turbine exit: (a) increase (b) decrease (c) remains the same
Heat supplied ; Decrease and this is because the latent heat been supplied will decrease when there is an increase in pressure
Heat Rejected ; Decrease
cycle efficiency ; Increase, the increase in the cycle efficiency increases in a very significant amount/rate because cycle efficiency = power output / heat input
