How much does water weigh approximately per gallon?

Water weighs approximately 8.3 pounds per gallon at standard temperature and atmospheric pressure. This value is essential in various fields, including hydraulics and boiler systems, as it helps professionals calculate the weight of water when designing systems and managing their operations.

Understanding the weight of water is crucial for applications in high-pressure boiler systems because it allows for accurate calculations of steam output, pressure, and thermal dynamics. The standard weight of 8.3 pounds per gallon is derived from the density of water, which is about 62.4 pounds per cubic foot.

In high-pressure applications, this knowledge aids in ensuring that the equipment can handle the weight of the water being used and helps in determining the appropriate storage tank sizes and piping systems.
