SUMMARY

The density of water is approximately equal to its weight density due to the relationship between mass and volume. In English units, the weight density of fresh water is about 62.5 pounds force per cubic foot, which translates to a mass density of approximately 1.99 slugs per cubic foot when divided by the acceleration due to gravity (32.2 ft/s²). This equivalence is crucial for understanding hydrostatic pressure and hydrostatic force in fluid mechanics.

PREREQUISITES
  • Understanding of hydrostatic pressure principles
  • Familiarity with weight density and mass density concepts
  • Basic knowledge of fluid mechanics
  • Proficiency in English unit conversions
NEXT STEPS
  • Research the principles of hydrostatic pressure in fluid mechanics
  • Learn about the differences between weight density and mass density
  • Explore the applications of density in calculating hydrostatic force
  • Study unit conversions in fluid dynamics, particularly in English units
USEFUL FOR

Students and professionals in engineering, physics, and environmental science who are studying fluid mechanics and the properties of water.

Why is the density of water almost the same as its weight (in English units)? This isn't really a homework question per se, but it's somewhat germane to what I'm doing right now (hydrostatic pressure and hydrostatic force).

[Edit]
Or at least part a of the first question on page 5 here seems to suggest so:

Because you have used the weight density of fresh water, which is approx. 62.5 pounds force per cubic foot. The mass density of fresh water is approx. 62.5 / 32.2 = 1.99 slugs per cubic foot.
 
Alright then. Thanks.
