Poiseuille's Law Calculation

You can change any of the following parameters. After entering the data, please click on the quantity you want to calculate using the formula above. Various parameters do not apply until you click on the quantity you want to calculate. In the case of differential pressure: x 10 ^ Pa = kPa

Volume flow = cm 3 / s = in 3 / s = liter / min = ft 3 / min = US gallons / min. The default value is assigned to a parameter that does not give a value. You can change any default value during the exploration process.

In non-ideal fluid dynamics, Hagen-Poiseuille's equation, also known as Hagen-Poiseuille's law, Poiseuille's law, or Poiseuille's equation, is an incompressibility through long cylindrical tubes and a physics giving Newton laminar flow It is a rule. Fluid pressure drop constant section It can be successfully applied to the alveolar air flow or through a pipette or hypodermic injection needle flow. It was independently tested by JeanLéonardMarie Poiseuille and Gotthilf Heinrich Ludwig Hagen in 1838 and was published by Poiseuille between 1840 and 1841 and 1846.

It is moved by the pressure difference to be given by T Newtonian fluid. Non-Newtonian fluid does not follow Poiseuille's law because viscosity is related to speed. The rationalized (laminar) flow assumption is incorporated into Poiseuille's law. When turbulence occurs, it is necessary to calculate the flow rate using Poiseuille's law. If turbulent flow occurs during flow, volumetric flow will decrease greatly. Consider a circuit in which the potential V between both ends of the resistor R generates the current I. Next, the flow rate is determined by the ratio of potential to resistance.

Flow and pressure variables can be calculated in a fluid flow network using hydrodynamic ohmic analogy. This method can be applied to both stable and transient flow conditions. In the linear laminar flow regime, Poiseuille's law describes the hydraulic resistance of the pipe, but in the turbulent region the relationship between pressure and flow is nonlinear. The compatibility of the formula can be expressed by a triangle with V (voltage) at the top, I (current) at the top, R (resistance) at the far right. The line dividing the left and right parts represents multiplication, and the upper and lower delimiters mean division (hence the division bar).
