Work can be produced by passing the vapor phase of a two-phase substance stored in a tank through a turbine as shown in the given figure. Consider such a system using R-134a, which is initially at 80°F, and a 16-ft3 tank that initially is entirely filled with liquid R-134a. The turbine is isentropic, the temperature in the storage tank remains constant as mass is removed from it, and the R-134a leaves the turbine at 10 psia. How much work will be produced when the half of the liquid mass in the tank is used? Use data from tables.
