Water flows in a flexible tube of radius 1.5 cm at the floor level of a house. The tube is joined a second tube of smaller radius (1.2 cm), which runs to a floor 7.2 m above. If the pressure in the lower tube is 214 kPa, and the pressure in the upper tube is 107 kPa, what is the speed of water in the upper (smaller radius) tube? (can you please write the units of pressure and density in the bernoulli equation because the units confuse me a lot)

2 parts! thanks :) 1. A water pipe with an inner diameter of 2.5 cm carries water into the basement of a house at a speed of 0.88 m/s and a pressure of 180 kPa. If the pipe tapers to an inner diameter of 1.2 cm and rises to the second floor 7.2 m above the input level, what is the speed of the water flow at the second floor? Your answer should be in m/s, but enter only the...

A bathtub spigot in a top floor apartment lies 20 m above street level, where water is pumped into the apartment building. The pipe that leads into the building has an inner radius of 0.57 cm , which tapers to 0.40 cm at the bathtub spigot opening. The speed of the water leaving the spigot is 12 m/s . (The density of water is 1000 kg/m 3 .) Assume the water flows without viscosity. (a) What is the speed of...
