Q = flow rate = velocity*area
= 5.44 *( pi /4) (2/100)^2
Q * t = volume
I just need help with c
A long horizontal hose of diameter 4.2 cm is connected to a faucet. At the other end, there is a nozzle of diameter 2 cm. Water squirts from the nozzle at velocity 24 m/sec. Assume that the water has no viscosity or other form of energy dissipation.
a) What is the velocity of the water in the hose ?
5.44 m/s
b) What is the pressure differential between the water in the hose and water in the nozzle ?
273203.2 Pa
c) How long will it take to fill a tub of volume 110 liters with the hose ?
? sec
