Poundal/square Foot
The poundal per square foot (pdl/ft^2) is a unit of pressure representing the force of one poundal applied over an area of one square foot.
History/Origin
The poundal is an imperial unit of force introduced in the 19th century as part of the foot-pound-second system, primarily used in engineering contexts. The unit pdl/ft^2 was used historically in mechanical and civil engineering to measure pressure but has largely been replaced by SI units.
Current Use
The poundal per square foot is rarely used in modern practice, having been largely replaced by the pascal (Pa) in scientific and engineering applications. It may still appear in legacy systems or specific regional engineering contexts.
Inch Water (60°f)
Inch water (60°F), symbol inAq, is a unit of pressure measuring the height of a water column at 60°F that exerts a pressure equivalent to one inch of water column.
History/Origin
The inch water unit originated in the United States as a practical measurement for low-pressure applications, particularly in HVAC and fluid systems, based on the height of a water column. Its use has been standardized in various industries for measuring small pressure differences.
Current Use
It is currently used in fields such as HVAC, pneumatic systems, and low-pressure fluid measurements to quantify small pressure differences, especially in the United States.
