Question

Fluid flows at 2.0 m/s through a pipe of diameter 3.0 cm. What is the volume flow rate of the fluid in m^3/

Answer 1

Volume flow rate =
`1.41 * 10^(-3)m^3/s`

Step-by-step explanation:

The volume flow rate through a channel can be gotten by multiplying its area and its velocity.

The channel under consideration is a circular channel. Hence, the cross-sectional area can be calculated by using the relation for calculating the area of a circle

Cross-sectional area =
`\pi * d^(2)/4`

`A = \pi * (3* 10^-2)^2 /4 = 7.07 * 10 ^-4 m^2`

volume flow rate=
`A = 7.07 * 10 ^-4 m^2 X 2.0 = 1.41 * 10^(-3)m^3/s`

Volume flow rate =
`1.41 * 10^(-3)m^3/s`
