(Answered) 1 a jet boat traveling at 12 ms takes in 008 m3s of water

Academics

1. A jet boat traveling at 12 m=s takes in 0.08 m3=s of water and discharges it at 24 m=s faster than the boat's speed. Estimate the thrust produced and power required.

2. The deflector of Fig. 4.4 changes the direction of a 60 mm · 24 cm sheet of water with V1 ¼ 30 m=s such that a ¼ 60o. Calculate the force components of the water on the deflector if
(a) it is stationary
(b) it moves away from the jet at 20 m=s
(c) it moves into the jet at 20 m=s
