Steam at 2000 psi and 1200 deg F enters a turbine operating at steady state. Partway through the turbine, 34% of the entering mass flow is extracted at 700 psi and 600 deg F. The rest of the steam exits the turbine as a saturated vapour at 1 psi. The turbine develops 7.3 x 106 Btu/h while heat transfer to the surroundings occurs at a rate of 4.4 x 104 Btu/h. Neglecting changes in kinetic and potential energy; determine the mass flow rate of steam entering the turbine in lbm/s.
