5. For the subsonic axial-flow air expander specified, calculate the stagnation and static pressures and temperatures and the Mach number at the rotor-inlet plane (figure P2.5). Also find the rotor rotational speed and the nozzle-inlet blade height for constant-outer-diameter blading. Sketch the form of the complete turbine expansion on an enthalpy-entropy chart. The axial velocity will be constant at this design point. Mass flow, m = 2 kg/s Nozzle-inlet stagnation temperature, Tuni = 400 °C. Absolute nozzle-inlet stagnation pressure, Po,ni = 3 bars(= 3 x 105 N/m²) Mean diameter, dm = 0.25 m. Blade height at rotor entry, 1 = 0.1dm(= 1/2[ds - dn]). Flow angle at nozzle exit, a₁ = 70° to axial direction. Drop in stagnation pressure in nozzle, Apo = 0.05 bar Rotor peripheral speed at mean diameter, um = 0.5x (component of nozzle outlet velocity, Ce,1).

1- Calculate the percent energy distribution in a steam generator that goes into steam, losses to flue gas. The steam generator receives 480 short ton coal per day. The heating value of coal is 5600 KJ/kg. 833000 KJ/kg of water enter steam generator at 175 bar and 230 °C and leaves as steam at 180 bar and 540 °C . Combustion air enters at 27 °C and flue gases leave at 175 °C. The air to fuel ratio by mass is 20:1. Assume that the flue gases have the same variable specific heat as air.
