Γ U o c 2 / U o o U Γ c c o U 2 / 2 / 2 (i) Calculate the lift L ow and the lift coefficient C ( ≡ L 5 . 0 /( U c ) , for the hydrofoil in L o ow open water in terms of , U o and c. (ii) Again, this hydrofoil operates at a distance c 2 / over the bottom. Obtain L and C b L b in this case. (iii) Calculate the ratio C L b / C L in terms of . What is this value for = ? 1 . 0 ow...
