A tube is run from the bottom to the top of the Grand Canyon (a depth of 1800 m). If the
pressure at the top is 1.0X105 Pascals and the pressure at the bottom is 1.1X105Pascals, what must the velocity of the fluid be at bottom if the velocity at the top is 2 m/s?
How can the opening having a cross-sectional area of 0.5 m2 be adjusted to get water to come
four times as fast?

Water flows through a pipe that gradually descends from a height of 6.78 m to the ground. Near the top, the cross-sectional area is 0.4 m2, and the pipe gradually widens so that its area near the ground is 0.8 m2. Water leaves the pipe at a speed of 16.8 m/s. What is the difference in the water pressure between the top and bottom of the pipe?

A large diameter closed top tank is filled with a depth of 3 meters of a fluid (density 1200 kg/m3). A small pipe leading from the bottom of the tank must carry the fluid some height above the fluid level in the tank. a) If a pressure of 2.5 Atmospheres is maintained in the space above the fill line in the tank how high above the fill line can the pipe carry the fluid and still provide an exit speed...

1) A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume...
