The volume flow rate (Q) of water through a pipe can be calculated using the formula:
Q = A * v
where A is the cross-sectional area of the pipe and v is the velocity of water.
The cross-sectional area of the pipe can be calculated using the formula for the area of a circle:
A = πr^2
where r is the radius of the pipe.
Substituting the given values, we get:
r = 0.0250 m
A = π(0.0250 m)^2 = 0.0019635 m^2
v = 1.50 m/s
Now, we can calculate the volume flow rate:
Q = A * v = 0.0019635 m^2 * 1.50 m/s = 0.002944 m^3/s
Rounding off to 3 significant figures, the volume flow rate is 0.00294 m^3/s.
