Question

Consider a large vertical plate with a uniform surface temperature of 100°C suspended in quiescent air at 25°C and atmospheric pressure. (a) Estimate the boundary layer thickness at a location 0.28 m measured from the lower edge. (b) What is the maximum velocity in the boundary layer at this location and at what position in the boundary layer does the maximum occur? (c) Using the similarity solution result, Equation 9.19, determine the heat transfer coefficient 0.25 m from the lower edge. (d) At what location on the plate measured from the lower edge will the boundary layer become turbulent?
