Required information

The upper surface of a $55-$cm$-$thick solid plate $(k=237\frac{W}{m}*K)$ is being cooled by water with temperature of $20C.$ The upper and lower surfaces of the solid plate maintained at constant temperatures of $60C$ and $120C,$ respectively.

Given: The thermal conductivity of the solid plate is given as $k=237\frac{W}{m}*K.$

The thermal conductivity of water at the film temperature of $T_f=\frac{(T_{s,1}+T_{})}{2}=\frac{(60+20)C}{2}=40C$ is $k_{\text{f}\text{l}\text{u}\text{i}\text{d}}=0\mathrm{.}631\frac{W}{m}*K$

Determine the water convection heat transfer coefficient. $($You must provide an answer before moving to the next part.$)$

The water convection heat transfer coefficient is $\frac{W}{m^2}*k$
