1. Using the Steam Tables, determine the heat absorbed by the boiler (KW) and Wsf when subcooled water at pressure = 5 Mpaa (subcooled by 64 deg C measured at the boiler inlet), is superheated to 100 degrees SH at the same pressure. Flow rate is at 10 cubic meters per minute. Ans.: a) Qa = b)Wsf= Hint: Use v at compressed water temp. at boiler inlet to convert to mass flow rate. Process is isobaric (Constant Pressure, where Q=m x AH).
