The term "differential pressure" refers to fluid force per unit, measured in pounds per square inch (PSI) or a similar unit subtracted from a higher level of force per unit. This calculation could be taken for pressures inside and outside a pipe or simply in different places along a flow path. This calculation has applications in the drilling industry.
Know MoreMeasuring differential pressure along a line helps drilling professionals identify the precise point of a blockage or to determine whether reservoir fluids are about to start backing into a wellbore, which can interfere with drilling operations. Keeping an eye on pressure at various points along a fluid line is vital for operational safety.

Full Answer >One inch of water, as measured using a pressure gauge at four degrees Celsius, is equivalent to 0.036127291827 pounds per square inch (PSI). This conversion can be found at OnlineConversion.com.
Full Answer >Converting from pounds per square inch to pascals is a simple unit conversion problem that can be solved in a short amount of time with pencil and paper or calculator. Simply multiply the known information by the conversion factor, cancel the units and solve the equation.
Full Answer >Forces are measured by using devices such as bathroom scales and spring balances, also known as force meters or Newton meters. When the mass and acceleration of an object are given, forces can also be measured using the equation F = ma, where "F" indicates the force, "m" denotes the mass and "a" represents acceleration.
