1. Water from a garden hose is sprayed against your car to rinse dirt from it. Estimate the force that the water exerts on the car. List all assumptions and show calculations.

2. A Pelton wheel vane directs a horizontal, circular cross-sectional jet of water symmetrically as indicated in Fig. P5.74 and Video V5.6. The jet leaves the nozzle with a velocity of 100 ft/s. Determine the x-direction component of anchoring force required to

(a) hold the vane stationary,

(b) confine the speed of the vane to a value of 10 ft/s to the right. The fluid speed magnitude remains constant along the vane surface.
