A pump circulates water through a system of connected pipes on a house from the basement to the top floor. The pump is located in the basement and drives water at 3.93m/s through a 6.99 cm diameter pipe at a gauge pressure of 425000 Pa. What will be the pressure (in kPa) in a 3.19 cm diameter pipe on the top floor, 21.6 m above the pipe? Please show work!

A 1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 0.50 cm. Liquid flows through the first segment at a speed of 4.0 m/s. What are the speeds in the second and third segments? What is the volume flow rate through the pipe? If all three parts of the pipe are at the same height and the pressure in the first segment is recorded at 80 kPa, what is the pressure in the second and third segments of the pipe?

A horizontal tube consists of a 7.0-cm diameter pipe that narrows to a 2.0-cm-diameter throat. In the pipe, the water pressure is twice atmospheric pressure and the water flows with a speed of 0.40 ms. What is the pressure in the throat, assuming that the water behaves like an ideal fluid? The density of water is 1000 kg/m^3, and atmospheric pressure is 1.01 X 10^5Pa
