Fuel Supply 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 diameter -
Volume in Gallons = 0.0034 x D² x L
D = inside diameter of pipe in inches, L = length in inches

Velocity in Feet Per Second = ( 0.408 x flow (gpm) ) ÷ D²
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 specific gravity

Specific Gravity of Oil = 0.85 approximately

Thermal Expansion of Oil = 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 ) ÷ 231

Head & Pressure Equivalents

The specific gravity of the liquid must be considered when converting pressure from feet of water to P.S.I. Here are some typical conversion figures:
1 P.S.I. = 2.30 feet of water (specific gravity 1.0)
1 P.S.I. = 2.88 feet of oil (specific gravity 0.8)
