A rigid, insulated tank fitted with a paddle wheel is filled with water, initially a two-phase liquidvapor mixture at 20 lbf/in.2 , consisting of 0.07 lb of saturated liquid and 0.07 lb of saturated vapor. The tank contents are stirred by the paddle wheel until all of the water is saturated vapor at apressure greater than 20 lbf/in.2 Kinetic and potential energyeffects are negligible. For the water, determine the(a) volume occupied, in ft3.(b) initial temperature, in 8F.(c) final pressure, in lbf/in.2(d) work, in Btu
