A9-m^3 tank contains nitrogen at 17°c and 600 kpa. some nitrogen is allowed to escape until the pressure in the tank drops to 410 kpa. if the temperature at this point is 15°c, determine the amount of nitrogen that has escaped. the gas constant for nitrogen is 0.2968 kpa-m /kg-k. the amount of nitrogen

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
