Reheating increases the enthalpy and entropy of the steam entering the turbine which allows more power to be extracted from the turbine for a given condenser pressure. Wouldn't simply superheating the inlet to a single turbine have the same effect?Question 3Select one:a.No superheating will require the addition of more heatb.No super heating will increase the entropy but it will not increase the enthalpyc.Yes both will have the same effects but superheating would reduce the quality of steam in the turbined.Yes but superheating would involve a higher turbine inlet temperaturee.Yes but superheating will not allow the use of inter-cooling

Consider a simple ideal Rankine cycle with fixed boiler and condensor pressures. What is the effect of super heating the stream to a higher temperatureQuestion 9Select one:a.heat supplied will increase, heat rejected will remain the same, turbine work output will increase and moisture content leaving turbine will decreaseb.heat supplied will increase, heat rejected will increase, turbine work output will stay the same and moisture content leaving turbine will decreasec.heat supplied will increase, heat rejected will increase, turbine work output will increase and moisture content leaving turbine will decreased.heat supplied will increase, heat rejected will increase, turbine work output will increase and moisture content leaving turbine will stay the samee.heat supplied will increase, heat rejected will decrease, turbine work output will increase and moisture content leaving turbine will decrease

When a simple Rankine cycle is modified to include reheating for the same mass flowQuestion 1Select one:a.the pump work remains the same, the heat supplied is increased, the heat rejected is increased, the total turbine work increases, and the quality of steam leaving the turbine decreasesb.the pump work remains the same, the heat supplied is increased, the heat rejected stays the same, the total turbine work increases, and the quality of steam leaving the turbine decreasesc.the pump work remains the same, the heat supplied is increased, the heat rejected is increased, the total turbine work increases, and the quality of steam leaving the turbine increasesd.the pump work remains the same, the heat supplied remains the same, the heat rejected is increased, the total turbine work increases, and the quality of steam leaving the turbine increasese.the pump work remains the same, the heat supplied remains increases, the heat rejected stays the same, the total turbine work increases, and the quality of steam leaving the turbine increases

A throttling valve is used in the ideal refrigeration cycle because ____________Question 5Select one:a.it is impossible to expand a liquid vapour mixture with a turbineb.the use of a turbine would require more work input to operatec.the use of a turbine improves the cooling power of the cycle, but would substantially increase the cost and complexityd.it provides an increase in entropy which corresponds to an additional heat input from the low temperature reservoir

Which of the following statements regarding a Rankine cycle with reheating are TRUE? (a) increase in average temperature of heat addition (b) reduction in thermal efficiency (c) drier steam at the turbine exit :

Consider a simple ideal Rankine cycle and an ideal Rankine cycle with three reheat stages. Both operate between the same pressure limits. The maximum temperature is 900K in the simple cycle and 650 K in the reheat cycle. Which do you think will have the higher thermal efficiency?Question 2Select one:a.simple cycleb.reheat cyclec.both will have the Carnot efficiencyd.it is impossible to tell without more information
