Question

The reheat factor depends upon
A. initial pressure and superheat
B. exit pressure
C. turbine stage efficiency
D. all of these

Answer 1

D)all of these
because it takes energy transfer

Answer 2

The reheat factor depends upon D. all of these.

What is the reheat factor?

• It is described as the comparison between the cumulative heat loss and the adiabatic heat loss across the whole turbine cycle.
• The kind and efficiency of the turbine affect the reheat factor's value.
• The reheat factor has a value in the range of 1.1 to 1.5.
• The cumulative heat drop to isentropic enthalpy decrease ratio is known as the reheat factor.
• The stage efficiency, final pressure, beginning pressure, and steam condition all affect the reheat factor's value.
• The temperature of the atmosphere has no bearing on it.
• The cumulative heat is the sum of the heat decreases in each stage of a multistage steam turbine with continuous expansion through the stages. The reheat factor is the relationship between the cumulative heat and the adiabatic drop from the beginning condition to exhaust pressure.
