Chemical engineering. the 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 2000 psia. the gas expands through a turbine, and the outlet gas from the turbine is fed to a boiler furnace at 100° c and 1atm at a rate of 15,000 ft^3/min. estimate the inlet flow rate to the turbine in ft^3/min using kay's rule. what percentage error would result from the use of the ideal gas equation of state at the turbine inlet?
