Air escapes from a high-pressure bicycle tire through a hole with diameter

Air escapes from a high-pressure bicycle tire through a hole with diameter d =
0.254 mm. The initial pressure in the tire is pt = 620 kPa (gage). (Assume the temperature
remains constant at 27°C.) The internal volume of the tire is approximately
4.26 X 10 4 m3 , and is constant. Estimate the time needed for the pressure in the tire
to drop to 310 kPa (gage). Compute the change in specific entropy of the air in the
tire during this process. Plot the tire pressure as a function of time.
