If water flows along both sides of a 5 m-long flat plate with a velocity of 60 m/s at 20oC, what will be the boundary layer thickness (cm) at a position 4 m from the leading edge? Indicate whether the boundary layer is laminar or turbulent. Calculate the total drag force (N or kg m/s2) on the plate if each surface of the plate is 550 m2.

In a lab experiment for a flat plate zero-pressure gradient boundary layer it is desired to find the friction coefficient (Cf) at location x=1 m from the leading edge of the plate. In order to do this, the momentum thickness of the boundary layer is measured at two locations 0.005m on either side of x=1m. the momentum thickness is measured to be 1.638 mm at x=0.995m and 1.652mm at x=1.005m, respectively, when the approach or free-stream velocity is 5m/s. a)...
