Specific enthalpy and velocity of steam at inlet and exit of a steam turbine, running under steady state, are as given below:

$\begin{array}{ccc} & \underline{Specific \: enthalpy (kJ/kg)} & \underline{Velocity \: m/s} \\ \text{Inlet steam condition} & 3250 & 180 \\ \text{Exit steam condition} & 2360 & 5 \end{array}$

The rate of heat loss from the turbine per $kg$ of steam flow rate is $5$ $kW$. Neglecting changes in potential energy of steam, the power developed in $kW$ by the steam turbine per $kg$ of steam flow rate, is

  1. $901.2$
  2. $911.2$
  3. $17072.5$
  4. $17082.5$
