If the flow under the water skiing board is to be maintained in a laminar flow, propose a maximum speed for the boat to pull the water skier. Assume the length of skiing board contacting with the water surface is constant at 1.2 m. Vwater = 0.8 × 10^-6 m^2 /s b) Show the distribution of skin friction coefficient along the skiing board at the velocity obtained in Q1(a). c) Calculate the frictional drag coefficient of the water skiing board at the velocity obtained in Q1(a).  d) If the boat pulled the water skier at one hundred times the velocity obtained in Q1(a), estimate the additional power required (in percentage) to pull the water skier.
