The turbine takes in steam with an enthalpy of hA $=2\mathrm{.}80$ MJ$/$kg at $40$ m$/$s$.$ A steam water mixture exits the turbine with an enthalpy of $1\mathrm{.}73$ MJ$/$kg at $15$ m$/$s$.$ If the heat loss to the surroundings during this process is $500$ J$/$s$,$ determine the power the fluid supplies to the turbine. The mass flow through the turbine is $0\mathrm{.}8$ kg$/$s$.$
