Question:
A vertical pistoncylinder device contains lbm of gas. The gas has an initial volume of ftThe piston, with a mass of lbm and crosssectional area of ft is in equilibrium with the gas. The outside ambient pressure is atm. The gas now undergoes a process in which the volume increases to ft and the specific internal energy decreases by Btulbm Assume a quasiequilibrium process in which piston movement is slow with no acceleration. Friction between the piston and cylinder is negligible. Include p V diagrams.
Determine:
a Work Btu during the process magnitude and direction
b Heat transfer Btu during the process magnitude and direction
