That is the reason people can worship their job, their money, their family, their belly, etc. And that is reason people can give worship to those other than Jehovah.
The old standard was 100 linear feet per minute (lfm), and this is still stated in the International Fire Code (IFC). This air velocity is calculated with the spray paint booth empty and using a cross-sectional area of the air flow direction. The more current codes require a minimum of 4 air exchanges per minute for wet or solvent-based paints. Powdercoat booths are required to have 60 lfm.
The most physical way to do the calculation is to consider the air mass (dry air) flow rate balance. Nevertheless it is also allowed to consider the volume flow rate balance when possible. Cases where using the mass flow rate is mandatory are: ï£§ air heating systems, ï£§ air conditioning systems.
