Problem #1 Model a submarine as a flat plate by 'unwrapping' the submarine (then the width of the flat plate would be the circumference of the submarine). The diameter of the submarine is 20 m and it is 70 m long. At cruising speed, the submarine moves at 20 m/s. Assume that the flow is tripped to turbulent at the front of the submarine. (a) Calculate the disturbance thickness, displacement thickness, and momentum thickness at the rear of the submarine. (b) Calculate the shear drag on the submarine at cruising speed. (c) Calculate the power that would be required to overcome this drag force.
