Tesla pump

Nikola Tesla developed his turbine to produce energy using steam as the moving fluid. His claim that a given turbine would work well with either steam or fluids is not correct, since the spacing between disks must be close to the thickness of the boundary layer of the fluid, which depends on viscosity and pressure.
