He product gas from a coal gasification plant consists of 60.0 mole% CO and the balance H2; it leaves the plant at 150°C and 135 bar absolute. The gas expands through a turbine, and the outlet gas from the turbine is fed to a boiler furnace at 100°C and 1 atm at a rate of 425 m 3 / min 425m3/min. Estimate the inlet flow rate to the turbine in f t 3 / min ft3/min, using Kay’s rule. What percentage error would result from the use of the ideal-gas equation of state at the turbine inlet?
