Consider air in an truck tire maintained at a pressure of 220 kPa (gage). The atmospheric pressure is 94 kPa. The air in the tire is at a temperature of 25 oC. A 4 mm diameter hole develops in the tire wall, due to a puncture. Approximating the flow out of the hole as isentropic, determine the initial mass flow rate of air leaving the tire [kg/sec].
