Sena works as a food engineer in a company that produces frozen fruits and vegetables. The company exports abroad, especially by freezing fresh strawberries, but it consumes a lot of energy for the freezing process. In order to reduce energy consumption and cost, Sena installed an adiabatic, reversible steam turbine in the company's facility. Steam enters this turbine at a speed of $3$ kg$/$s$,$ a temperature of $400\backslash$deg C and a pressure of $5000$ kPa and exits at a pressure of $50$ kPa. The power obtained from this turbine is used to freeze strawberries at $-36\backslash$deg C$.$ If the heat transfer rate $($Q$)$ given by the cooler to the environment is $11\mathrm{.}97$ MW

a$)$ Draw a diagram of the process and state all your assumptions

b$)$ b$)$ Calculate the power $($W$)$ obtained from the turbine

c$)$ Calculate the amount of heat transfer $($Q$)$ withdrawn from the cold environment.

d$)$ Calculate the temperature of the environment $($TH$)$ in $"\backslash$deg C$"$

If the specific entropy $($s$)$ of superheated steam at $6$ MPa pressure is $6\mathrm{.}80$ kJ$/$kg K$,7=?,$ h$?$
