Air (diatomic, MW = 28.8664 g/ mol) in an automobile tire is maintained at a pressure of 220 ka (gage) in an environment where the atmospheric pressure is 94 kPa. The air in the tire is at the ambient temperature of 25°C. A 4-mm-diameter hole develops in the tire as a result of physical damage. Approximating the gas flow as isentropic, determine the initial mass flow rate (kg/min) of air through the leak. Check first for choking.
