Recall the assumptions made during the derivation.
Question 5.
A fluid flows from a large diameter pipe to a smaller one, causing a pressure drop of 15 kPa. Determine the velocity increase if the flow rate remains constant.
Show hintHide hint
Keep in mind the relationship between area and velocity in pipes.
Question 6.
