The idea is to use the maximum power available from the motor to power the pump and calculate the torque to the hydraulic pump.

Pump Input:
==Calculations==
  Torque at rated input (5HP and 3600 RPM): torque = 5 HP * 33000 / 2 * pi * 3600 = 7.29 ft-lb
  Solve for pump RPM: RPM = .303 HP * 33000 / 2 * pi * 7.29 ft-lb =~ 218


Engine Specs:
===Torque===
  Displacement: 420cc Bore: 90, Stroke: 66.
   Torque (ft-lb) = HP * 33000 / 2 * pi * RPM = 16 * 33000 / 2 * pi * 3600 = 23.34 ft-lb
  Max Output: 16.0 HP / 3600 RPM.
   Max Torque: 28.5 Nm / 23.34 ft/lb.
  Shaft Size: 1" Diameter, 2-3/4" Long, 1/4" Keyway,
  Shaft End: 3/8" Size 24 UNF - Drilled and Tapped
  Measurement from Center of Shaft to Base: 5"
  Fuel Tank Capacity: 1.75 Gallons
  Fuel Consumption: 1/2 Gallon Per Hour (at 1/2 load)
  Dry Weight: 77 lbs
  Recommended Fuel Type: Gasoline - 87 Octane Rating Or Better
 
Pump Specs:
  Disp: 0.92 cu. in. / rev.
  Pump Type: Gear
  Rotation: CW
  Pressure: 3000 PSI Max.
  Speed: 3600 RPM Max.
  Flow: 7.17 GPM @ 1800 RPM and 2000 PSI.
  Mount: 2 bolt SAE A
  Shaft: 5/8" 9T spline, 1-1/4" long.
  Inlet Port: SAE 16
  Outlet Port: SAE 10
  Size: 4-1/2" x 5-1/8" x 4-5/8"
  Shpg: 12 lb.


===Hydraulic Fluid Flow===
===Hydraulic Fluid Flow===
Use pump specs to calculate displacement:
   RPM * CIPR = 0.92 CIPR * 3600 RPM / 231 cu-in/gal = 14.33 GPM
   RPM * CIPR = 0.92 CIPR * 3600 RPM / 231 cu-in/gal = 14.33 GPM

Torque

 Torque (ft-lb) = HP * 33000 / 2 * pi * RPM = 16 * 33000 / 2 * pi * 3600 = 23.34 ft-lb

Hydraulic Fluid Flow

 RPM * CIPR = 0.92 CIPR * 3600 RPM / 231 cu-in/gal = 14.33 GPM
