Turbulence can be used to reduce the rate of flow of a fluid.
Explain this in terms of energy transfers.

This is just an idea, but if you imagine introducing some turbulence to a flow, you're putting energy into vortices within that flow.

A yo-yo on a string spinning around a point has an average position at the centre which doesn't move, but the energy isn't zero.

Try to think about partitioning the energy of a fluid flow which is initially 100% translational, and introducing some sort of turbulent vortex within it.

(My guess...)

okay, so this is what i think. imagining, we have a water flowing down the river at constant speed and it has a laminar flow. when we introduce turbulent flow to it, some of the kinetic energy gets converted into internal (heat) energy due to masses of friction between streamlines. so kinetic energy is reduced, which is why the rate of flow of the fluid is also reduced.
so is this the explanation which they're looking for? :/
