the subject is thermodynamics 2. please make the solution clear and understandable. thanks

A reheat-regenerative engine receives steam at 207 bar and 593°C, expanding it to 38.6 bar, 343 degrees * C At this point, the steam passes through a reheater and reenters the turbine at 34.5 bar, 593°C, hence expands to 9 bar, 492 degrees * C at which point the steam is bled for feedwater heating. Exhaust occurs at 0.07 bar. Beginning at the throttle (point 1), these enthalpies are known (kJ/kg): ht= 3511.3 h4= 322.9 h2 = 3010.0 h5 = 2308.1 h6= 163.4 h2 = 3082.1 h3= 3662.5 h7= 742.83 h7=723.59 h4= 3205.4 For ideal engine, sketch the events on the Ts plane and for 1 kg of throttle steam, find (a) the mass of bled steam, (b) the work, (c) the efficiency, and (d) the steam rate. In the actual case, water enters the boiler at 171°C and the brake engine efficiency is 75% (e) determine the brake work and the brake thermal efficiency. (f) Let the pump efficiency be 65%, estimate the enthalpy of the exhaust steam.
