Solve the below:
Q: Water at a velocity of 2.5 m/s flows parallel to a 1-m-long horizontal, smooth and thin flat plate. Determine the local thermal and hydrodynamic boundary-layer thicknesses, and the local friction coefficient, at the midpoint of the plate. What is the rate of heat transfer from the plate to the water per unit width of the plate, if the surface temperature is kept uniformly at 150°C, and the temperature of the main water stream is 15°C?
GIVEN
Water flows over a smooth and thin flat plate
Water velocity (U∞) = 2.5 m/s
Length of plate (L) = 1 m
Surface temperature (Ts) = 150°C
Water temperature (T∞) = 15°C
ASSUMPTIONS
Steadystate
