F is the force in newtons (N); and A is the area in square meters (m{eq}^2 {/eq}). Use Example 1 to apply the above formula in calculating pressure. Example 1 A 50-kg woman tried standing on one foot while wearing a thin-heeled shoe with an area of 0.50 cm{eq}^2 {/eq}...
Osmotic pressure and its concept are very important in chemistry mainly in physical chemistry. If two solutions of having different concentrations and are separated by a semipermeable membrane, then an interesting osmosis process will happen. This articl
Pressure (P or p) is a scalar quantity. Pressure Formula In equations, pressure is denoted by the capital letter P or the lowercase letter p. Pressureis aderived unit, generally expressed according to the units of the equation: P = F / A where P is pressure, F is force, and A is ...
A barometer is an instrument used to measure the atmospheric pressure in an environment. The pressure of the atmosphere is helpful in forecasting the changes in the weather of a region. As the air pressure changes with the altitude, the barometer can also be used to calculate height above the...
