A horizontal, uniform, circular cross-section jet of air at 20 C and 1 atm strikes a flat plate as shown below. The jet velocity is steady at 40 m/s and the jet diameter is 30 mm. The air velocity magnitude stays constant as the air flows over the plate's surface in the directions shown. The face of the plate lies in a vertical plane, such that the weights of the plate and air are not relevant. The anchoring force FA holds the plate stationary against the jet. Calculate the fraction of the total mass flow along the plate in each of the directions shown. That is, calculate the ratios m/m and m3/m. ANS: 0.94 and 0.06 V = 40 m/s V3 Dj = 30 mm = 30 90 FA V2
