A water hose 2 cm in diameter is used to fill a 20 litre bucket. If it takes 1 minute to fill the bucket, then the speed v at which the water the water leaves the hose is,

Solution

$V = A v t = a r e a \times v e l o c i t y \times t i m e$

$⟹ v = \frac{V}{A t} = \frac{20 \times 10^{- 3}}{π \frac{(0.02)^{2}}{4} \times 60}$

$⟹ v = 1.06 m / s$

If it takes 5 minutes to fill a 15 litre bucket from a water tap of diameter $\frac{2}{\sqrt{π}}$ cm then the Reynolds number for the flow is (density of water = $10^{3} k g / m^{3}$ and viscosity of water = $10^{- 3}$ Pa.s) approximately

V=Avt=area×velocity×time⟹v=VAt=20×10−3π(0.02)24×60⟹v=1.06m/s
