An adiabatic gas turbine expands air at 1350 kpa and 600 degrees celsius to 130 kpa and 157 degrees celsius. inlet area is 0.4 m square & velocity is 50 m/s. exit area is 1 m square, mass flow rate (kg/s) & power produced (mw) are, respectively a) 108,48 b) 115, 51 c) 99, 44 d) 118,52

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.
