This document discusses the application of the continuity equation in fluid mechanics to calculate volumetric flow rates between two points.
Extract
[...] When the lance works, point B is in contact with the atmosphere, therefore the pressure at point B is atmospheric pressure: [...]
[...] Fluid Mechanics Let us write the continuity equation of volumetric flow rate between A and QVA = QVB Therefore we have: VA.SA = VB.SB So it: We make the digital application by ensuring that the units are in m. VA = VB.0.03²/15² = VB. 0,000004 On will therefore neglect VA before VB and we will consider it as null. [...]
