- Water flows through a pipe of cross-sectional area, A, with a speed of 4 m/s. The pipe then widens to a cross-sectional area of 2A. What is the speed of the flow in the wider section? O A) 2 m/s B) 16 m/s C) 8 m/s D) 4 m/sMany cities have water tanks raised high off the ground to produce pressure for their residence. If one such water tank had a diameter of 4.40 m and its water level being 20.7 m above the ground. What would be the pressure at ground level if the water was not being used? (static)If at ground level a faucet had an opening with a diameter of 2.00 cm, how fast would the water come out of the faucet?Water at a gauge pressure of 3.8 atm at street level flows into an office building at a speed of 0.67 m/s through a pipe 5.5 cm in diameter. The pipe tapers down to 2.5 cm in diameter by the top floor, 18 m above, where the faucet has been left open. - Calculate the flow velocity in the pipe on the top floor. Assume no branch pipes and ignore viscosity. - Calculate the gauge pressure in the pipe on the top floor. Assume no branch pipes and ignore viscosity.
