Question

A standard steel tube, 1.5 25-mm OD 3 1.5-mm wall (Appendix G.2), is carrying 19.7 L/min of oil. Calculate the velocity of flow

Answer 1

0.864 m/s

Step-by-step 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
