Saturated water vapor at 150 °C is isothermally condensed to a saturated liquid in a piston-cylinder device. Calculate the work and heat transfer done (per unit mass) during this process. Question 4 Not complete Marked out of 5.0 Flag question Question text (a) (Tsat = 150 ºC) Submit your answer for the work transfer in kJ/kg (enter numerical value only without units). Follow the sign convention of work transfer being positive out of the system and negative into the system. Check Question 5 Not complete Marked out of 5.0 Flag question Question text (b) (Tsat = 150 ºC) Submit your answer for the heat transfer in kJ/kg (enter numerical value only without units). Follow the sign convention of heat transfer being positive into the system and negative out of the system.

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.
