This Fluid Resistance conversion equation converts an input measure of fluid resistance (pressure/volume) into other units of fluid resistance. The pressure units are typically in pascals (Pa) or millimeters of mercury (mmHg), and the volume units range from cubic millimeter up to cubic meter.
To perform conversion:
For example: if you enter 205.8 and leave the default input units as `("Pa"*s)"/"L` as your input fluid resistance unit, the display will show a resultant 205.8 `("Pa"*s)"/"L` output. If you then select `("mmHG" * "min")" / cm"^3` as your output units, the output is automatically converted to 0.0000257271868108789 `("mmHG" * "min") / "cm"^3`.
Example: if you enter 1000 and select `("mmHG" * s)"/"L` as input units, you can convert to `("Pa"*"min") "/" L` by simply selecting `("Pa"*"min") "/" L` as the output unit. vCalc would convert 1000 to 2222.03333333333 `("Pa"*"min") / L`
Fluid Resistance is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. Fluid Resistance is sometimes referred to as drag (or air resistance when the fluid is air) or. The effects of fluid resistance may be exhibited between fluid layers or fluid surfaces or between a fluid and a solid surface.
Fluid resistance depends on velocity. Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow and the cause of fluid resistance is viscous friction.
Fluid Resistance decreases fluid velocity relative to a solid object with which the fluid interacts.some
The units of fluid resistance supported by vCalc for conversion are:
