Unformatted text preview: The boundary layer on each surface of the plate is laminar. Assume that the velocity profile may be approximated as linear. Determine the drag force on the plate. 4. The foils of a surface-piercing hydrofoil watercraft have a total effective area of 0.7 m 2 . Their coefficients of lift and drag are 1.6 and 0.6, respectively. The total mass of the craft in running trim is 1800 kg. Determine the minimum speed at which the craft is supported by the hydrofoils. At this speed, find the power required to overcome water resistance. If the craft is fitted with a 110 kW engine, estimate its top speed....
