Question
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.
The properties of air at this
temperature are given as; specific
heat capacity Cp = 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.
