Question

A water tunnel with a depth of 15" with a top that is open to the atmosphere is used to study the boundary layer on a flat plate. The surface of the water has a pressure of 2116 Ibf/ft2 and a velocity of 3 ft/s The density of water is 1.94 slugs/ft3. and its dynamic viscosity is 2.00 times 10-5 Ibf-s/ft2. What is the stagnation pressure at the bottom of the test section? The flat plate is 3 ft. long and I ft. wide. Assuming the flow is purely laminar, compute the drag force on this plate, accounting for both sides. What is the boundary layer thickness at the end of the plate? Assume that the velocity of the flow is increased to 20 ft/s and the critical Re for transition to turbulent flow is 1.000.000. Compute the transition location on the plate and the total drag generated by this flow.
