A single acting steam engine has a swept volume of 0.05 m3 and cut-off occurs at 0.4 of the stroke. The steam in the main is saturated at 13 bar, and the engine exhaust to condenser at 0.7 bar. Neglecting the effects of clearance volume, and assuming that the expansion occurs according to PV=constant, determine the percentage reduction in work output per machine cycle when the steam is throttled to 7 bar before it enters the steam chest.

A single acting steam engine has a swept volume of 0.05 m3 and cut-off occurs at 0.4 of the stroke. The steam in the main is saturated at 13 bar, and the engine exhaust to condenser at 0.7 bar. Neglecting the effects of clearance volume, and assuming that the expansion occurs according to PV=constant, determine the percentage reduction in work output per machine cycle when the steam is throttled to 7 bar before it enters the steam chest.
