Carbon dioxide gas is allowed to pass through a diffuser of an inlet diameter 2 in and an outlet diameter of 4.5 in. The pressure at inlet is 46 psi and that at the outlet is 10 psi. The densities of the gas at the inlet and outlet are 0.356 lb/ and 0.077 4 lb/, respectively. If the inlet velocity of the gas is 350 ft/s, determine (a) mass flow rate, and (b) exit velocity
