Over a short time interval \Delta t, This is a statement of the principle of mass conservation for a steady, one-dimensional flow, with one inlet and one outlet. This equation is called the continuity ...

volumetric flow rate and pipe diameter, as set out in Poiseuille’s equation. Corrections are then carried out for pressure and temperature in order to produce a standardized mass flow rate. These are ...

The mass melt flow rate from Method A is calculated using the mass of the extrudate(s), as shown in the equation below: where (g) is the mass in grams of material, collected over time (sec). In order ...
