The diagram below shows an inclined tube manometer connecting two pipes. Determine the change in elevation of the mercury in the left leg of the manometer below if the pressure in pipe A decreed by 10 Kpa while the pressure in the pipe B remains constant​

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.
