please help me with this one

0.90 P 0.7bar (10) Question 3 (30%): As shown in Fig. 03, steam at 8 MPa, 440C, enters a turbine operating af steady state with a volumetric flow rate of 236 P80 bar Turbin mmin. Twenty percent (2096) of the entering mass flow 7,440C exits through a diameter of 0.25 m at 6 MPa, 400'C. The rest CAV), - 236 m/min exits through a diameter of 1.5 m with a pressure of 70 kPa and a quality of 90%. Determine; D,- 1.5 in (a) the mass flowrate at the inlet and each exit ducts (kg/s) (b) the velocity at the inlet and at each exit duct (m/s) if the diamenter of the inlet duct is 0.25 m, () the power output developed by the turbine, neglecting the potential energy effects and assuming the stray heat transfer between the turbine and the surrounding to be 1,000 kW. 0.20 P60 bar T400C D, 0.25 m (10%) (10%)
