Fluid Power Formulas

Pressure			Mechanical Horsepower
	P = pressure (PSI) F = force (lb.) A = area (in²)			HP = mechanical horsepower d = distance (ft.) F = foce (lb.) t = time (seconds)
Volume (cylinder)			Mechanical Horsepower
	V = volume (in³) A = area (in²) [note: either Ap or Ae]			HP = mechanical horsepower F = force (lb.) V = velocity
Piston Area (cylinder)			Hydraulic Horsepower
	Ap = piston area Dp = piston diameter			HP = hydraulic horsepower Q = flow (gpm) P = pressure (PSI)
Rod Area (cylinder)			Motor Horsepower
	Ar = rod area Dr = rod diameter			HP = motor horsepower S = speed (rpm) T = torque (lb.-in.)
Effective Area			Heat
	Ae = effective area Ap = piston area Ar = rod area			H = heat (Btu/hour) HP = hydraulic horsepower
Piston Rod Speed (cylinder)			Flow (SCFM)
	V = velocity Q = flow (gpm) A = area (in²)			Q = flow (ft³/min.) V = cylinder volume (in³) CR = compression ratio t = stroke time (seconds)
Flow (cylinder)			Compression Ratio
	Q = flow (gpm) n = rod speed (in/min) A = area (in²) [note: either Ap or Ae]			CR = compression ratio Pg = gauge pressure (PSIG) Pa = atmospheric pressure (PSIA)
Pipe Flow			Air Motor Speed

Pressure Drop in Pipes			Pneumatic Cylinder Rod Speed
	GPM = gallons per minute V = viscosity (SSU) D = diameter			V = cylinder rod speed (in./min.) S = stroke (in.) t = stroke time (seconds)
Torque			Hydraulic Tank Cooling
	T = torque (lb.-in.) F = force (lb.) d = distance (in.)			HP = horsepower Aw = wetted area (ft²) T = oil temp - ambient air temp.
Motor Torque			Flow Coefficient (Cv)
	T = motor torque (lb.-in.) P = pressure (PSI) Disp = motor displacement (in³/rev)			Cv = flow coefficient Q = SCFM G = specific gravity of flow medium (G = 1 for air) Tabs = absolute temp (460+°F) P = pressure drop (PSI) static to static pressure Po = outlet pressure = inlet press - P Pa = atmospheric pressure
Motor Shaft Speed
	RPM = motor shaft speed (rpm) Q = flow (gpm) Disp = motor displacement (in³/rev)
Work (ft.-lb.)
	W = work (ft.-lb.) d = distance (ft.) F = force (lb.)
Power (ft.-lb./sec)
	d = distance (ft.) F = force (lb.) t = time (seconds)
