We can find the volume of flow rate through the hose from the formula:


Q=Av,Q = Av,

here, A=πr2A = \pi r^2 is the cross-sectional area of the hose, vv is the speed of the water.

Then, we get:


Q=πr2v,Q = \pi r^2v,Q=π(0.025 m)28ms=0.016 m3s.Q = \pi \cdot (0.025 \ m)^2 \cdot 8 \dfrac{m}{s} = 0.016 \ \dfrac{m^3}{s}.

Answer:

Q=0.016 m3s.Q = 0.016 \ \dfrac{m^3}{s}.
