Super heated steam at T$1(\backslash$deg C$)$ and corresponding specific enthalpy H$^1$ and $10\mathrm{.}0$ bar pressure is combined with saturated steam at T$2(\backslash$deg C$)$ and $7\mathrm{.}0$ bar pressure in a ratio $1\mathrm{.}86$ kg of steam at $10\mathrm{.}0$ bar $/1\mathrm{.}0$ kg steam at $7\mathrm{.}0$ bar. The product stream is at $250\backslash$deg C and $7\mathrm{.}0$ bar. The process operates at steady state. What is the specific enthalpy H$^1$ associated with stream $1$ assuming that the blender operates adiabatically?
