In a horizontal pipe, the average velocity of the fluid is 0.5 m/s, the pressure drop is 10 Pa, and Re is 1000. What is the velocity on the centerline of the pipe? ( ) m/s. If the average velocity increases to 1 m/s, the pressure drop becomes ( ) m/s. What formula is used for the calculation? Thank you.
In actual engineering design, these are all meaningless designs that waste time
Take a look at the optimal approach in chemical engineering principles; it’s very simple to apply – just two formulas are needed.
Answer: 1m/s, 40pa. Is that correct?
