Q2 Steam at a pressure of 12 bar and a dryness friction of 0.8 is to be discharged through a convergent-divergent nozzle to a back pressure of 0.2 bar. The mass flow rate through the nozzle is at a rate of 12 kg/kW-hr. If the turbine develops 190 kW, determine: (i) the throat pressure, (ii) the number of nozzle required, the diameter of nozzle at throat being 6-5 mm, and (ii) suitable exit diameter of the nozzle, assuming that 15% of the overall isentropic enthalpy drop reheats the steam in the divergent portion of the nozzle.
