Question

Water flowing through a 2.9 cm -diameter pipe can fill a 100 L bathtub in 3.8 min .

What is the speed of the water in the pipe?

Express your answer using two significant figures.

Answer in m/s please!!

Answer 1

Answer #1

Here ,

let the speed of water in the pipe is v

volume flow rate = cross sectional area * speed

volume/time = area * time

100 * 10^-3/(3.8 * 60) = pi * (0.029/2)^2 * v

solving for v

v = 0.664 m/s

the speed of the flow is 0.66 m/s
