Description

Inch of Water (inH₂O): HVAC and Fluid Mechanics

The Inch of Water (inH₂O) is a unit of pressure defined as the pressure exerted by a column of water one inch high, approximately equal to 249.0889 Pascals. It is widely used in the HVAC industry to measure air pressure in ducts and ventilation systems, as well as in fluid mechanics for low-pressure measurements.

Standard Atmosphere (atm): A Reference Pressure

The Standard Atmosphere (atm) is a unit of pressure defined as 101,325 Pascals. It represents the average atmospheric pressure at sea level and is used as a reference point in various scientific calculations. The atm is particularly useful in chemistry and physics for standardizing measurements involving gases and reactions under 'standard' conditions.
