Extend Prob. P5.30 as follows. Let the maximum mass flow m . again be a function of tank pressure p0 and temperature T0, gas constant R, and nozzle diameter D, but replace cp by the specific heat ratio, k. For an air tank at 190 kPa and 330 K, with a 2-cm nozzle diameter, experiments show a mass flow of 0.133 kg/s.
(a) Can this data be used to correlate an oxygen tank?
(b) If so, estimate the oxygen mass flow if the tank conditions are 300 kPa and 450 K, with a nozzle diameter of 3 cm
