Flow in Pipes Flow of fluids in pipes is described by the steady state mechanical energy balance. Steady state means that properties are not changing with time. So the balance can be written as 0 = + + + + W FR EOS PE KE θ out in

Kinetic Energy Term (KE) The change in kinetic energy is the energy change brought about by a change in velocity between the inlet and the outlet. For turbulent flow this is expressed as Velocity is related to volumetric throughput or flux. For a liquid this is: 2 2 1 v KE = 2 2 4 2 d q d q A q v π π = = =
Kinetic Energy Term (KE) For a liquid, the kinetic energy change is: If the pipe diameter does not change, - = - = 4 4 2 2 4 4 2 1 1 8 1 1 4 2 1 in out in out d d q d d q KE π π 0 = KE

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
