Question:

For the propeller and conditions described in Problem 14.10, determine the thrust and the power input. Assume ρ = 1.2 kg/m3.

Data from Problem 14.10

A propeller 2 m in diameter, like the one for which characteristics are given in Fig. 14.3, is to be used on a swamp boat and is to operate at maximum efficiency when cruising. If the cruising speed is to be 40 km/h, what should the angular speed of the propeller be?
