A rigid, well-insulated tank contains a two-phase mixture of ammonia with 0.0025 ft³ of saturated liquid and 1.5 ft³ of saturated vapor, initially at p₁ = 70 lb/in². A paddle wheel stirs the mixture until only saturated vapor at higher pressure, p2, remains in the tank. Kinetic and potential energy effects are negligible. Determine the pressure p₂, in lb/in², and the amount of energy transfer by work, in Btu. Step 1 Your answer is correct. Determine p2, in lb/in². P2 90 Hint Step 2 * Your answer is incorrect. lb/in² Determine the amount of energy transfer by work, in Btu. W12-54.94 Btu Attempts: 1 of 4 used
