In Prob. 2.5, assume that the rate at which air is being pumped into the tank is 0.5 lb m /s. Consider the instant in time at which there is 1000 lb m of air in the tank. Assume that the air temperature is uniformly 50°F at this instant and is increasing at the rate of 1°F/min. Calculate the rate of change of pressure at this instant.
