Calculate Speed from Distance and Time

* Differential Pressure Calculator

In some cases, it may be necessary to insert a resistance in the pipeline to
restrict the flow to a certain value at a given pressure drop. The Differential

Pressure Calculator calculates the K value needed to achieve a differential
pressure for a specified flow rate.

* Ideal Gas State Equation

Ideal Gas State Equation was first stated by Benoît Paul Émile Clapeyron
in 1834. It determines the relationship between its pressure, volume and

The Equation of State of an Ideal Gas, which is a good approximation to
real gases at sufficiently high temperatures and low pressures; that is,
PV = RT where P is the pressure, V is the volume per mole of gas, T is
the temperature, and R is the gas constant.

Any equation that relates the Pressure, Temperature, and Specific
Volume of a substance is called the equation of state.

* Critical Oil Flow Rate Calculator

Mayer & Garder were the first to proposed this concept for determining
the Critical oil flow rate for a gas-oil isotropic reservoir with the perforated
interval at the lower bottom of the oil zone.
