Q7: A turbine is supplied with Steam at 40 bar, y00'c,wwhich expands through the turbine in Steady flow to an exit pressure of 0.2bar and adryness fraction of o.93. The inlet velocity is negligible but the Steam leaves at high velocity through a duct of oil4 m cross-Sectioral area.If the mass flow rate is 3 lgis, and the mechanical etticiency is 90%- Calculate the horse power output of the turbine - Show that the process is isreve- rsible and calculate the change of entropy,negligible the heat losses from the turbine.

|Q7: A turbine is supplied with Steam at 4o bar, y00'c,which
ex pands tdrough the turbine in Steady flow to an
of 0.2bar and adryness fraction of 0.93. The inlet velocity is
negligible but the Stram leaves at high velocity through a duct
of oil4 m' cross-Sectioral area.If the mass flow rate is 3 legis,
exit
pressure
and the mechanical efficiency is 90% - Caleulate the horse
power output of the turbine - Show that the process is isreve-
rsible and calculate the change of entropy, negligible the heat
losses from the turbine.
