Question

3. Air at a velocity of 100m/s with a temperature of 20°C flows over the top surface of a flat plate that is maintained at 58°C. The plate has a length of 0.15 m and a width of 0.1 m. What is the rate of heat transfer from the plate to the air? $\rho$=1kg/m³, $\mu$=200x10⁻⁷Ns/m², k=0.03W/mK, $C_p$=1kJ/kgK, Pr=0.7

Step 1

$Re_L = \frac{\rho V L}{\mu}$ where: $\rho$ = density of air = 1 kg/m³ V = velocity of air = 100 m/s L = length of the plate = 0.15 m $\mu$ = dynamic viscosity of air = 200 x 10⁻⁷ Ns/m² $Re_L = \frac{(1 kg/m³)(100 m/s)(0.15 m)}{200 \times 10^{-7} Ns/m²} = 7.5 Show more…
