Question
What’s the correct answer for this please?
Transcribed Image Text:Wind flows over a flat plate of length L = 25
mm and width W = 8 mm. The plate is
maintained at a constant temperature of 32 °C
on both sides using an electric heater
generating heat at a rate of Q = 0.5 W which is
dissipated to air from both sides of the plate.
Consider the temperature of the wind/air as
20 °C and assume that the wind speed does not
exceed 100 m/s.
%3D
The properties of air at this temperature are
given as; specific heat capacity C, = 1.005
kJ/kg-K, thermal conductivity k = 0.0253 W/m-
K, Density p = 1.19 kg/m³, and kinematic
viscosity v = 1.522 x 10-5 m²/s.
%3D
If Prandtl number, Pr= 0.72, determine the flow
Reynolds number.
