Question

The tank contains air at a temperature of 20∘C∘C and absolute pressure of 800 kPakPa . Using a valve, the air escapes with an average speed of 160 m/sm/s through a 25-mmmm-diameter nozzle.

If the volume of the tank is 1.25 m3m3, determine the rate of change in the density of the air within the tank at this instant. Gas constant of the air is R� = 286.9 J/(kg⋅K)J/(kg⋅K).
Express your answer using three significant figures.
