8. The fresh water intake in a reservoir has a cross-sectional area of 0.800 m2 and receives water flowing at a speed of 0.500 m/s. At the outlet, a vertical distance of 200 m below the intake, the cross-sectional area is 0.020 m. Calculate the pressure difference between the inlet and outlet. (Answer: 1.76 x 10 Pa)

1. As a stream of water flows, the cross-sectional area of the stream becomes smaller. If it initially moves with a speed of 1.8 m/s and then the cross-sectional area decreases to one-fourth of the original area, what is the water speed in this narrowed part of the stream?____ m/s 2. (As water falls, its speed increases, due to the acceleration of gravity. If you make a steady stream of water flow from a faucet, you will see that the...

A water intake at a pump storage reservoir (the figure) has a cross-sectional area of 0.642 m. The water flows in at a speed of 0.480 m/s. At the generator building, at distance D = 119 m below the intake point, the cross-sectional area is smaller than at the intake and the water flows out at 9.67 m/s. What is the difference in pressure between inlet and outlet? Revivir Generator building Outlet Number units
