WebMay 22, 2024 · Pressure is a measure of the force exerted per unit area on the boundaries of a substance. The standard unit for pressure in the SI system is the Newton per square meter or pascal (Pa). Mathematically: p = F/A where p is the pressure F is the normal force A is the area of the boundary Pascal is defined as force of 1N that is exerted on unit area. WebOne pascal is a small pressure; in many cases, it is more convenient to use units of kilopascal (1 kPa = 1000 Pa) or bar (1 bar = 100,000 Pa). In the United States, pressure is often measured in pounds of force on an area of one square inch— pounds per square inch (psi) —for example, in car tires.

WebMay 9, 2024 · A bicycle tire is inflated to 65 psi. What is this pressure in atmospheres? Solution: 1 atm = 14.696 psi. Set up the conversion so the desired unit will be canceled out. In this case, we want atm to be the remaining unit. pressure in atm = (pressure in psi) x (1 atm/14.696 psi) pressure in atm = (65/14.696) atm. pressure in atm = 4.423 atm. WebP ∝ (1/V) Where P is the pressure exerted by the gas and V is the volume occupied by it. This proportionality can be converted into an equation by adding a constant, k.
