Answer:
0.864 m/s
Explanation:
We calculate using this formula
Q = A/v
We make v subject of the formula
v = Q/A
Q = volume of flow
A = area
The metric based sizes for dimensions of steel and copper tubing has that at 25mm OD x 1.5
A = 3.801x10^-4
Q has been given as 19.7L/min of oil
When we put these into the formula
V = [19.7 x 1/60000]/3.801x10^-4
= 0.000328333/0.0003801
= 0.8638 m/s
Approximately 0.864
