Hi,

I was working on my hwk, but would like to double check my answer. Could you please solve it?

H3.3 A frictionless vertical pistoncylinder device contains 5.5 lbm of H20 initially at T1 = 150F and p1 = 500 psia. The device is heated until the volume is V2 = 4.4 ft3. Assume a quasiequillibrium process which occurs slowly with no acceleration as the piston moves. Kinetic and potential energy eects are negligible. Determine: a. work [Btu] during process (indicate magnitude and direction) b. heat transfer [Btu] during process (indicate magnitude and direction)
