Fluid Database within Pipe Flow Mobile AppsPipe Flow Mobile Software Applications come with an integrated fluid database that contains fluid properties for a range of common liquids or common gases (depending on if the App is for liquids or gases).
Users can select a standard fluid from the fluid database and this can be used when performing a calculation.
If the fluid does not exist in the fluid database, then new fluid properties can be defined manually and optionally added to the database.
Fluid Properties: Liquids and Gas Data
The fluid database will display either Liquid or Gas Data depending on the App and whether it is for liquids or gases. Liquids are considered to be incompressible in that the density of the liquid does not change under pressure, whereas gases are compressible and pressure will affect the density of the gas. Temperature changes will affect the density of both liquids and gases.
When working with gases, there is a Gas Data Calculator that can compute the fluid properties for common gases over a range of different temperature and pressure conditions. This allows the user to define their own gas data for a specific condition and this data can be saved and added to the fluid database so that it can be used with future calculations.
The fluid database includes the following fluid properties:
Kinematic viscosity in Centistokes
Density in g/cm³ OR (kg/m³) x (1/10³);
Viscosity relationship: Centistokes = (Centipoise / Density)
The density of water in g/cm³ is 1. Relative density is the ratio of the density (mass per unit volume) of a particular fluid to the density of given reference fluid. For liquids, Specific Gravity normally means the relative density of a fluid compared to the density of water, whereas for gases, Specific Gravity normally means the relative density of a gas compared to the density of air. In modern science the term often used is Relative Density.
