The ideal gas at pressure and temperature (300 kpa and 227C")respectively, flows steadily in pipe .The mass and volume flow rates (17.6 kg/s, 0.5543 m'/s). If the gas is cooled at constant pressure that's leads to droop the temperature at the exit pipe 177C Determine a) the flow rate in kmol/s and the density of the gas b)The volume flow rate at exit of the pipe.
