What are losses before disposal of an asset?

There are two kind of losses in fluid flow, major loses and minor loses. As minor losses are independent of fluid viscosity, in the case of liquid helium, which has no viscosity, will minor losses will occur?

• Liquid helium below certain temp and conditions becomes super fluid, it show zero viscosity. Flow once started sustains for days. Minor losses like entry losses exit losses are independent of fluids intensive property like dynamic viscosity, so will super fluid also exhibit minor losses?

• Answer:

  Behaving as a super-fluid and being a superfluid are different. The viscosity will certainly be low, but not zero. If it were zero, we could just touch the fluid slightly and it would stay in a state of turbulence till Judgement day and beyond. Now you should understand-why does a fluid stop? Because it loses the energy it requires to keep moving. Hence if the fluid stops at any point of time, we can reasonably assume that there are losses. In absence of a more specific context, I think we can safely say that there will be minor losses, no matter how negligible.
