The average heat transfer co efficient for flow of 100o C air over a flat plate is calculated by observing the temperature time history of a 3mm thick copper slab exposed 100o C air. In one test run, the initial temperature of the plate was 210 oC, and in 5 minutes the temperature decreased by 40 oC. Determine the heat transfer coefficient for this case. Also derive the equation used to determine heat transfer coefficient. Take the following properties of copper ρ = 8800kg/m3 , Cp = 400J/KgoC
