Question
Consider a parallel flow with velocity of 5 m/s and at ambient temperature of 20°C flows over a
flat plate.
(a) Calculate the average convection heat transfer rate subjected with an L= 200 cm long and
w = 200 cm wide flat plate for air flow (v = 16.69 ×10-6 m²/s, k = 26.9 × 10-3 W/m•K, Pr =
0.707) and surface temperature of Ts = 50°C.
(b) Calculate the average convection heat transfer rate subjected with an L = 10 cm long and
W =
10 cm wide flat plate for water flow (v = 5.543×10-7 m²/s, k = 0.643 W/m K, Pr =
3.56) and surface temperature of Ts = 80°C.
