Current Attempt in Progress

Steam enters a well$-$insulated turbine operating at steady state at $4$ MPa with a specific enthalpy of $3015\mathrm{.}4k\frac{J}{k}g$ and a velocity of $10\frac{m}{s}.$ The steam expands to the turbine exit where the pressure is $0\mathrm{.}07$ MPa $,$ specific enthalpy is $2300k\frac{J}{k}g,$ and the velocity is $90\frac{m}{s}.$ The mass flow rate is $4k\frac{g}{s}.$

Neglecting potential energy effects, determine the power developed by the turbine, in kW$.$
