Models of torpedoes are sometimes tested in a horizontal pipe of flowing water, much as a wind tunnel is used to test model airplanes. Consider a circular pipe of internal diameter 25.5 cm and a torpedo model, aligned along the axis of the pipe, with a diameter of 4.80 cm. The torpedo is to be tested with water flowing past it at 2.76 m/s. (a) With what speed must the water flow in the unconstricted part of the pipe? (b) Find the pressure difference between the constricted and unconstricted parts of the pipe.
