An ideal gas expands in an adiabatic turbine from 1200 K, 600 kPa to 700 K. Determine the turbine inlet volume flow rate of the gas, in m3/s, required to produce turbine work output at the rate of 200 kW. The average values of the specific heats for this gas over the temperature range are cp = 1.13 kJ/kg • K and cv = 0.83 kJ/kg • K. R 0.30 kJ/kg • K.
