4. Physical properties of the fluid
4.1 Parameters required to calculate the primary element
Determining the flow rate of a fluid using a depressurizer requires knowledge of its density at flow conditions upstream of the device and, in the case of a gas or vapour, its isentropic coefficient. The viscosity of the fluid is also required, whatever its type.
SCROLL TO TOP4.2 Density determination
Determining the density of the fluid is often the most laborious step in a primary element calculation, unless of course the process technicians provide...
