Problem \#3) (20 points) A worker pressurizes a rigid pipe ( 30mm inside diameter and 20m long) with dry air to check for the leaks. The temperature and the absolute pressure of the air in the pipe are 35C and 205 kPa. The worker returns 24 hours later and the absolute pressure has dropped to 183kPa, where the air temperature inside the pipe has decreased to 21C. Has the pipe leaked? If so, calculate the mass of air that has leaked through the fittings
