Question using Kay's Rule

  1. Mar 27, 2010 #1
    Hi I was wondering if anyone could help me with this material balance/gas behaviour question.

    "The product gas from a coal gasification plant consists of 60.0 mol% CO and the balance H2. It leaves the plant at 423.14 kelvins and 2,000 psia. The gas expands through a turbine and is fed to a boiler furnace at 373.15 kelvins and 101.325 kPa at a rate of 424.75 m3/min. Estimate the inlet flow rate to the turbine in m3/h, using Kay’s rule.
    What percentage error would result from the use of the ideal gas equation at the turbine inlet? "

    I have no idea how to start so any help would be much appreciated!

    To start, how about writing Kay's rule.

    Also right the values given, such as temperature, pressure, volumetric flow rate, and gas composition. The determine the unknown value for which one is solving.
