Question

Assuming neither the heat input nor work required by the pump do not change, what is the
new thermal efficiency of the power plant during this reduced work operation?

During nominal operation, the power plant operates with the following parameters.
kJ
= 2823.2 2
kg
kJ
Wpump,in = 4.05 kJ/kg
9in
9out = 1985.0
kg

Expert Solution

Step 1

Given data:

$q_{i n} = 2823.2 k J / k g q_{o u t} = 1985.0 k J / k g w_{p u m p, i n} = 4.05 k J / k g$

Need to determine the thermal efficiency of the power plant.
