(a) Water flows through a nozzle at a volumetric flow rate

(a) Water flows through a nozzle at a volumetric flow rate of 5xlpm. What is the diameter of the nozzle if the pressure drop measured across the nozzle is 1bar ? Consider the discharge coefficient to be 0.595 and the density of water is 998kg/m3. (b) Now, if water is replaced with methane gas flowing in a polytropic mode (k=1.2) through the same nozzle with an entrance pressure of 7MPa at the rate of 30m/s, how much will be the exit pressure and exit density? (c) What is the exit pressure at G max conditions, if the nozzle entrance pressure of methane gas is the same as the above
