# Hydraulic-motor torque and speed
# Scope: Fixed-displacement motor with supplied mechanical and volumetric efficiency.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

pressure = 10 MPa
displacement = 10 cm^3
flow = 5 L/min
mechanicalEfficiency = 0.85
volumetricEfficiency = 0.9

torque := pressure*displacement*mechanicalEfficiency/(2*pi) [N*m]
speed := flow*volumetricEfficiency/displacement*2*pi [rpm]

check torque target: torque >= 10 N*m

scenario alternative: pressure = 8 MPa
