High rise building smoke control and extraction (1):Discussion about unsuitable usage of differential pressure method and flow rate method for calculation of pressurized supply air volume for high ris

Analyses the existing problems when the differential pressure method and flow difference method are used in calculating the pressurized supply air volume for high rise buildings from the view point of hydrodynamic. Concludes that the two methods are not suitable for the calculation of pressurized supply air volume for high rise buildings.
