Unveiling the Mystery of 1714 in Hydraulics: Understanding its Significance

Welcome to our exploration of the constant 1714 in hydraulics! In this video, we'll unravel the origins of this seemingly magical number in the formula HP = (gpm × psi) / 1714, shedding light on its significance in hydraulic calculations. Let's dive into the world of hydraulic power!

The Role of 1714 in Hydraulic Formulas

The constant 1714 appears in various hydraulic formulas, particularly in equations relating to the calculation of hydraulic horsepower (HP). In the context of the formula HP = (gpm × psi) / 1714, 1714 serves as a conversion factor to convert units of flow rate (gallons per minute, gpm) and pressure (pounds per square inch, psi) into hydraulic horsepower.

Understanding the Origin of 1714

The origin of the constant 1714 can be traced back to the unit conversions involved in the formula for hydraulic horsepower. Specifically, 1714 is derived from the following unit conversions:

  • 1 horsepower (HP) = 550 foot-pounds per second (ft-lb/s)
  • 1 gallon of water weighs approximately 8.34 pounds (lb)
  • 1 minute (min) = 60 seconds (s)

By combining these unit conversions, we arrive at the factor of 1714:

HP = (gpm × psi) / 1714

Practical Applications of 1714

The constant 1714 simplifies hydraulic calculations by providing a standardized conversion factor for determining hydraulic horsepower based on flow rate and pressure. This allows engineers and technicians to assess the power output of hydraulic systems and components accurately.


While the constant 1714 may seem like just another number in hydraulic formulas, its significance lies in its role as a conversion factor for calculating hydraulic horsepower. By understanding its origins and applications, hydraulic professionals can utilize this constant effectively in their calculations and analysis.
