Question

Confine 1 lb of wet steam at 500°F and with an enthalpy of 800 Btu in a rigid container. Heat is applied until the steam becomes saturated. Determine (a) the initial pressure p₁, (b) quality x₁, (c) volume v₁, (d) the final pressure p2; and for the process, (e) W, (f) O.

Answer 1

Solution;

Given;

m=1lb=0.4536kg

$T_1=500°F=260°c$

$h_1=800Btu=844.032kJ$

$V_1=V_2$

From steam tables;
