Determine the maximum power a wind turbine may produce at the followingwind speeds: 1, 5 and 10 m/s.
Consider an airplane cruising at 1000 km/h to the right. If the velocity of exhaust gases is 700 km/h to the left relative to the ground, the velocity of the exhaust gases relative to the nozzle exit is (a) 1700 km/h (b) 1000 km/h (c) 700 km/h (d) 300 km/h (e) 150 km/h
A 100-ft3/s water jet is moving in the positive x-direction at 18 ft/s. The stream hits a stationary splitter, such that half of the flow is diverted upward at 45° and the other half is directed downward, and both streams have a final average speed of 18 ft/s. Disregarding gravitational effects, determine the x- and z-components of the force required to hold the splitter in place against the water force.
