Complete Question
Air at 40C flows over a 2 m long flat plate with a free stream velocity of 7m/s. Assume the width of the plate (into the paper) is 0.5 m. If the plate is at a co temperature of 100C,find:
The total heat transfer rate from the plate to the air
Answer:
Explanation:
From the question we are told that:
Air Temperature
Length
Velocity
Width
Constant temperature
Generally the equation for Total heat Transfer is mathematically given by
Where
h=Convective heat transfer coefficient
Therefore
