Mass Flow Rate Simply put, this defines the volumetric rate with which fluids flow (kgs-1). In a system where there is a fluid flow and no sources or sinks the the mass flow rate must be equal at all points within that system This yields the Equation of Continuity:
- where:
- ρ = density [kgm-3]
- A = cross sectional area [m2]
- v = velocity [ms-1]
|  | That is, if the pipe constricts, the fluid flows faster; if it widens, the fluid flows slower. This is, in effect a different interpretation of the law of conservation of momentum | Conversions | | | | | | | | 1 lbm s-1 | = | 0.454 kg s-1 | | 1 lbm h-1 | = | 1.26x10-4 kg s-1 | | 1 ton h-1 | = | 0.282 kg s-1 | | 1 slug s-1 | = | 14.6 kg s-1 |
