1. The thrust of a marine propeller Fr depends on water density p, propeller diameter D, speed of advancethrough the water V, acceleration due to gravity g, the angular speed of the propeller w, the water pressurep, and the water viscosity μ. You want to find a set of dimensionless variables on which the thrust coefficientdepends. In other wordsCT =FT· = ƒen(#1, #2, ...)pV2D2(a) What is k? Explain.(b) Find the 's on the right-hand-side of equation 1 if one of them HAS to be a Froude number gD/V²,(1)

Assume that the wall shear stress, Tw, created when a fluid flows through a pipe (see Figure a) depends on the pipe diameter, D, the flowrate, Q, the fluid density, p, and the kinematic viscosity, v. Some model tests run in a laboratory using water in a 0.2-ft-diameter pipe yield the Tw vs. Q data shown in Figure b.
