A school is supplied with water through a main pipe with A 7.00 cm diameter. A faucet located  h = 1.90 m  above the main pipe is 2.00 cm in diameter and can fill a 23.0 L container is 30.0 s. (a) What is the speed (in m/s) at which the water leaves the faucet (in m/s)?   (b) What is the gauge pressure (in Pa) in the 7.00 cm wide main pipe? (Assume the faucet is the only "leak" in the building.)

A sealed tank containing seawater to a height of 12.0 m also contains air above the water at a gauge pressure of 3.05 atm. Water flows out from the bottom through a small hole.  Calculate the speed with which the water comes out of the tank. Express your answer in meters per second.

Question 2. Water pipe with an inside diameter of 4.80 cm carries water at an ab- solute pressure of 5.60 x 10 Pa from the basement into the fourth floor of a house. The fourth floor is 9.50 m above the basement and the diameter of the pipe on the fourth floor is 2.50 cm and the water pressure is 4.25 x 105 Pa. a) Find the speed of flow as water enters from the basement. b) Find the speed of flow in the fourth floor. c) Find the volume flow rate through the pipe.

A factory is supplied with water through a main pipe with An 8.00 cm diameter. A faucet located h = 1.90 m above the main pipe is 2.00 cm in diameter and can fill a 25.0 L container is 30.0 s. (a) What is the speed (in m/s) at which the water leaves the faucet (in m/s)?   (b) What is the gauge pressure (in Pa) in the 8.00 cm wide main pipe? (Assume the faucet is the only "leak" in the building.)

A beaker is filled with an unknown liquid up to a depth of 10.00cm . The gauge pressure at the bottom of the beaker is measured to be 1540.00Pa . What is the density of the liquid contained in the beaker?

A pumping station uses a Venturi tube to measure the flow rate of gasoline. The density of the gasoline is p = 7.40 x 102 kg/m3, the inlet and outlet tubes, respectively, have a radius of 2.80 cm and 1.40 cm, and the difference in input and output pressure is P, - P, = 1.20 kPa. (a) Find the speed (in m/s) of the gasoline as it leaves the hose. m/s (b) Find the fluid flow rate in cubic meters per second. m3/s
