A speedboat on hydrofoils is moving at 20 m/s in a freshwater lake. Each hydrofoil is 3 m below the surface. Assuming, as an apporximation, frictionless, incompressible flow, find the stagnation pressure(gage) at the front of each hydrofoil. At one point on a hydrofoilm the is -75kPa(gage). Calculate the speed of the water relative to the hydrofoil at this point and the absolute water speed.
