1. The air in an automobile tire is maintained at a pressure of 220 kPa (gage) in an environment where the atmospheric pressure is 94 kPa. The air in the

tire is at25°C. A 4-mm diameter leak develops in the tire as a result of an accident.Approximating the flow as isentropic, determine the initial mass flow rate of air through the leak. (hint: Watch Video “Chapter 11-automobile tire.mp4")
