Problem 3 – Sparky needs helium for an experimental project. The helium is stored in a storage tank at 20°C and 300 kPa. The helium exits through a converging nozzle to the environment (100 kPa atmospheric pressure) and has 10 mm exit diameter. Determine the exit flow rate of the helium. Helium’s ratio of specific heats is 1.667. This is a compressible flow problem. Only use equations and tables from the textbook to solve this problem. Note the figures in the textbook and textbook appendices are based in air, not helium, and are not valid for this problem.
