Water circulates throughout a house in a hot-water heating system. If the water is pumped at a speed of 0.4 m/s through a 4-cm-diameter pipe in the basement under a pressure of 3.1 atm, what will be the pressure in a 2.2-cm-diameter pipe on the second floor 4.5 m above? Assume the pipes do not divide into branches. (Write the value with 2-decimal digits and SI unit.)

QUESTION 1
Water circulates throughout a house in a hot-water heating system.
If the water is pumped at a speed of 0.4 m/s through a 4-cm-diameter
pipe in the basement under a pressure of 3.1 atm, what will be the pressure
in a 2.2-cm-diameter pipe on the second floor 4.5 m above?
Assume the pipes do not divide into branches. (Write the value with 2-decimal digits and SI unit.)
Take density of water as
1000 kg /m3.
Hint:
AV1=A2V2
