Given: The thermal conductivity of the solid plate is given ask= 237 W/m K.
f2
(T,1+T)
= (60°C + 20°C)/2 = 40°C is kuid = 0.631
The thermal conductivity of water at the film temperature of T;
W/m/K.
Determine the water convection heat transfer coefficient.
The water convection heat transfer coefficient is
W/m2 -K.
