WebMay 8, 2024 · This is a key property as it is a different number from the solid-state density that is usually given on the data sheets. For instance, unpigmented or unfilled polycarbonate has a solid-state density of 1.20 g/cm 3, whereas the melt density of the material is 1.08 g/cm 3, or 90% of the solid-state density. This value is practically significant. WebIn physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol Q (sometimes V̇ ). It contrasts with mass flow rate, which is the other main type of fluid flow rate. iowa dxf file
