The thermal efficiency of a steam power cycle is determined

The thermal efficiency of a steam power cycle is determined to be 36%. Determine the heat rate of the cycle in SI and IP systems.

Solution :

Given efficiency = 36 %

In SI system

Heat rate is (3.6/0.36MJ/KWh) = 10 MJ/kWh

In IP system

Heat rate is (3412.1 Btu/KW.h )/ 0.36 = 9478 Btu/ KW.h
