According to experimental results for parallel airflowover
Chapter 9, Problem 9.110(choose chapter or problem)
According to experimental results for parallel airflowover a uniform temperature, heated vertical plate,the effect of free convection on the heat transferconvection coefficient will be 5% when GrL/Re2L?0.08.Consider a heated vertical plate 0.3 m long, main-tained at a surface temperature of 60?C in atmos-pheric air at 25?C. What is the minimum verticalvelocity required of the airflow such that free con-vection effects will be less than 5% of the heat trans-fer rate?
