Question

a garden hose of diameter 2cm is used to fill 1000 litre container in a time of 10 minutes.calculate the flow rate in cubic cm per second​

Answer 1

Answer: Flow rate 1670 cm³/s

Explanation: Cross section A = π · (2 cm)² = 12.56 cm²

V = 1000 l , t = 10 min = 600 s

dV / dt = 1000 l / 600 s = 1,67 l/s = 1670 cm³ /s

That was not asked,

dV / dt = vA and flow speed v = (dV/dt)/A = 133 cm/s
