Experiments Have Been Conducted On Three Geometrically Similar Air Foils Since Airfoils Are Thin The Fluid Flow Over A 1 (99.24 KiB) Viewed 26 times

Experiments have been conducted on three geometrically similar air-foils. Since airfoils are thin, the fluid flow over airfoils can be considered to be like flow over flat plate, i.e., the streamwise pressure drop can be neglected. The width of airfoils (perpendicular to air stream) is 1.0 m. Neglect the curvature of airfoils in your calculations. The results obtained from experiments are shown below: Airfoil No. 1 2 3 Length, L (m) 1 0.2 0.5 Velocity, U.. (m/s) 10 5 10 Air temp., Too (K) 300 300 300 p= 1 kg.m3 -3 k = 0.05 W.m-¹.

B- Calculate the heat transfer rate between airfoil No. 1 and the air stream μ = 10-5 Pa.s Pr = 0.7 Friction force, F (N) 1 0.1 ???
