One leg of mercury u-tube manometer is connected to a pipe containing water under a pressure of 120kpa. the mercury in this leg stands 0.5m below water and the mercury in other leg is open to air. specific gravity of mercury is 13.6 and density of water is 1000kg/ m^3 . the height of mercury in open leg is approximately

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.
