Steam at 1400 kpa and 350°c [state 1] enters a turbine through a pipe that is 8 cm in diameter, at a mass flow rate of 0.1 kg⋅s−1. the exhaust from the turbine is carried through a 15-cm-diameter pipe and is at 50 kpa and 100°c [state 2]. what is the power output of the turbine?
h1 = 3150.7 kj/kg v1 = 0.2004 m3/kg
h2 = 2682.6 kj/kg v2 = 3.4181 m3/kg

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
