A square plate maintained at 95 ° C experiences a force of 10.5
N when forced air at 25 ° C flows over it at a velocity of 30 m / s
. Assuming the flow to be turbulent and using Colburn analogy
calculate ( a ) the heat transfer coefficient and ( b ) the heat
loss from the plate surface . Properties of air at 60 ° C are : p =
1.06 kg / m³ , c = 1.005 kJ / kgk , v = 18.97 x 10-6 m² / s , Pr =
0.696
