During the preliminary design of a submarine, a designer assumes that the drag force will be equal to the drag on a streamlined body that has a diameter of 1.5 m and a length of 8 m. the design speed is 10 m/s, the submarine will operate in 10°c water (kinematic viscosity is η=1.31x10^-6 m^2/s), and the submarine will be powered by an electric motor with an efficiency of 90%. determine the power that will be consumed by the motor.
