Question

Question 13 A frictionless piston-cylinder device contains saturated liquid water at 25-psia pressure. Now 1000 Btu of heat is transferred to water from a source at 800°F, and part of the liquid vaporizes at constant pressure. Determine the exergy destroyed during this process. Assuming the surroundings to be at 70 °F and 14.7 psia.

A frictionless piston-cylinder device contains saturated liquid water at 25-psia pressure. Now 1000 Btu of heat is transferred to water from a source at 800Â°F, and part of the liquid vaporizes at constant pressure. Determine the exergy destroyed during this process. Assuming the surroundings to be at 70Â°F and 14.7 psia.
