Question

A long horizontal hose of diameter 3.2 cm is connected to a faucet. At the other end, there is a nozzle of diameter 1 cm. Water squirts from the nozzle at velocity 12 m/sec. Assume that the water has no viscosity or other form of energy dissipation.

1)What is the velocity of the water in the hose ?

1.17   m/s

2)

What is the pressure differential between the water in the hose and water in the nozzle ?

71718.75 Pa

3)

How long will it take to fill a tub of volume 100 liters with the hose ?

____________sec

Explanation / Answer

Ok now, from my previous post, I considered the length as 1.17m rather we must take 12m instead. By taking that we get from my previous calculations

volume will be 0.0386m3   approximately.

so the time will be 0.1/0.0386= 2.59 seconds.

Please check the previous calculations..
