A coolant fluid at 30°C flows over a heated flat plate maintained at a constant temperature of 100°C. The boundary layer temperature distribution at a given location on the plate may be approximated as T= 30 + 70 expt(-y) where y(in m) is the distance normal to the plate and fis in °C. If thermal conductivity of the fluid is 1.0 W/mK, the local convective heat transfer coefficient (in W/m2K) at that location will be

Verified Answer
A coolant fluid at 30°C flows over a heated flat plate maintained ...
Under steady state conditionsHeat transfer by conduction = Heat transfer by convection
∴ 
or 

But y = 0

or h(100–30) = k x (100 - 30)
or h = k = 1 W/m2K
