The pilot of an airplane reads the altitude 6400 m and the absolute pressure 45 kpa when flying over the city. calculate the local atmospheric pressure in that city in kpa and in mmhg. take the densities of air and mercury to be 0.828 kg/m3 and 13600 kg/m3, respectively. show this using the systematic solution method.

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.
