Does the turbulence of a fluid flowing through a pipe decrease with the distance from the entrance?

Consider a constant-diameter L-shaped pipe with an entrance and an exit. If water is being pumped into the pipe at a constant rate, the flow rate of the water at the exit must equal that at the entrance, correct? In addition, there must also be a loss of kinetic energy of the water due to friction loss and the bend of the pipe, also correct? If both of those statements are true, then the only way I can think of that the water could be losing kinetic energy is through a decrease in turbulence so I am wondering if it can be said that the turbulence of a fluid flowing through a pipe decreases over the distance of the pipe. If the flow through the pipe is completely laminar, is it possible for the fluid to lose kinetic energy?

• Whether or not turbulence exists depends on the Reynold's number. What Reynold's number exists for your example? Apr 5, 2017 at 19:08
• @DavidWhite I believe any Reynold's number above zero is sufficient for the question I'm trying to pose but not being a fluid dynamics expert I could be mistaken. I think the question I'm trying to ask is general enough that knowing a specific Reynold's number isn't necessary. Apr 5, 2017 at 20:55
• I think it increases as turbulence mounts Apr 5, 2017 at 23:36
