APPENDIX B - TECHNICAL DATA
Conversion Factors
1HP = 33,000 ft. lbs. per minute
1HP = 42.4 btu per minute
1HP = 0.746 kwhr (kilowatt hours)
1 U.S. gallon= 231 cubic inches
Pipe Volume varies as the square of the diam-
eter; volume in gallons = 0.0034 D
2
L where:
D=inside diameter of pipe in inches;
L=length in inches
Velocity in feet per sec.= 0.408
x
fl ow (gpm)
D

where:
D=inside diameter of pipe in inches
Atmospheric pressure at sea level = 14.7PSI
Atmospheric pressure decreases
approximately 0.41PSI for each one thousand
feet of elevation up to 23,000 feet.
Pressure (PSI) = feet head x 0.433 x specifi c
gravity
Specifi c gravity of oil is approximately 0.85.
Thermal expansion of oil is approximately
1 cubic inch per 1 gallon per 10°F rise in
temperature.
Hydraulic Formulas
Horsepower = GPM x PSI
1714
Torque (lb. in.) = CU IN./REV. x PSI
2
Torque (lb. in.) = HP X 63025
RPM
Flow (gpm) = CU IN./REV x RPM

Head and Pressure
Equivalents
When converting pressure from feet of water to
P.S.I., the specifi c gravity of the liquid must be
considered.
Here are some typical conversion fi gures:
1 P.S.I.=2.30 feet of water
(specifi c gravity 1.0)
1 P.S.I.=2.88 feet of oil
(specifi c gravity 0.8)
