Air at 22˚C and at atmospheric pressure flows over a flat plate at a velocity of 1.65 m/s. If the length of the plate is 2.179 m and its temperature is 98 ˚C, Calculate Heat rate by using exact and approximate methods both. What is the %age difference of the heat transfer rate values by these methods? Take width of the plate as unity. Properties given at 60˚C are as follows: Density: 1.058 kg/m3 , cp = 1.004 kJ/kg˚C, k= 0.02893 w/m˚C, Kinematic viscosity is 18.97 × 10-6 m2 /s

Question
Air at 22˚C and at atmospheric pressure flows over a flat plate at a velocity of 1.65 m/s. If the length
of the plate is 2.179 m and its temperature is 98 ˚C, Calculate Heat rate by using exact and approximate
methods both. What is the %age difference of the heat transfer rate values by these methods? Take
width of the plate as unity.
Properties given at 60˚C are as follows:
Density: 1.058 kg/m3
, cp = 1.004 kJ/kg˚C, k= 0.02893 w/m˚C, Kinematic viscosity is 18.97 × 10-6 m2
