Kent,
Tesla's diagram for the fluid propulsion unit is available in the book "
Tesla's big book of patents"
available at Barnes and Noble for about 17.00 US. This design features a
spiral star washer, 1/16" spaceing between the rotor sections, and a volute
housing. Smaller rotors mean faster rpm is necessary. If you consider the
speed at which the outside edge of the rotors is moveing you will get an
idea. A 1 foot diameter rotor section turning at one rpm is moving
approximately 3.14 foot per minute. A 10 foot diameter rotor section turning
at one rpm is moving at 31.4 foot per minute. You must assume the water is
moving at 1/2 the speed of the rotor section. The pressure is directly
related to the speed at which the water is moving. The volume is directly
related to the number of disks per rotor section + the speed of the water.

Sorry no exact figures. But many variables involved. Inlet diameter, outlet
diameter, incoming pressure, Head pressure, volute housing or not. Basically
the pump wants to eject water in all directions so a circular housing will
result in back pressure.
