Consider the open feed water heater $\text{(FWH)}$ shown in the figure given below:
Specific enthalpy of steam at location $2$ is $\text{2624 kJ/kg}$, specific enthalpy of water at location $5$ is $\text{226.7 kJ/kg}$ and specific enthalpy of saturated water at location $6$ is $\text{708.6 kJ/kg}$. If the mass flow rate of water entering the open feed water heater (at location $5$) is $\text{100 kg/s}$ then the mass flow rate of steam at location $2$ will be ________ $\text{kg/s}$ (round off to one decimal place).
