Air is flowing in parallel over the upper surface of a flat plate with a length of 4 m. The first half of the plate length, from the leading edge, has a constant surface temperature of 50°C. The second half of the plate length is subjected t a uniform heat flux of 86 W/m2. The air has a free stream velocity and temperature of 0.5 m/s and 10°C respectively. The properties of air at T= 30°C are k= 0.02588 W/m-K, v = 1.608 x 10-5 m2/s, and Pr = 0.7282. Air, V, T Constant T, = S50°C 86 W/m?

Question

Determine the local convection heat transfer coefficients at 1 m and 3 m from the leading edge.

Air is flowing in parallel over the upper surface of a flat plate with a length of 4 m. The first half of the plate length, from the leading edge, has a constant surface temperature of 50°C. The second half of the plate length is subjected to
a uniform heat flux of 86 W/m². The air has a free stream velocity and temperature of 0.5 m/s and 10°C respectively. The properties of air at Tf= 30°C are k= 0.02588 W/m-K, v = 1.608 × 10-5 m²/s, and Pr = 0.7282.
