2KLIMA Co.Flow and system stress should beknown factors in air flow. The flow isgas quantity flowing through thesystem during given time unit and is3 3measured as m /sec or m /h. Systemstress is the amount of energy thateach kg of gas must have in order to beable to flow through the system inparticular quantity per given time unit3and is expressed as J/kg or J/m .System characteristics are the relationbetween the flow and system stress.Some ratios of important ventilatorparameters arising from the law ofsimmilar flowA- At the change of number ofrevolutions:- Volume of flow has a linear relation inregard to the change of ventilator"snumber of revolutionsV1 n1=V2 n2- Pressure (static, dynamic and total) isin proportion to the square of change innumber of revolutionsD1 (n1) 2= 2 D2 (n2)- Required driving power supplied toventilator shaft is proportional to thecube of change in number ofrevolutionsP1 (n1) 3= 3 P2 (n2)B- At the change of air temperature:- Pressure alters in linear proportion ofair temperatureDp1 T1=Dp2 T2- Required driving power supplied toventilator shaft is in proportion tosquare of change to air temperatureP1 (T1)= 2P2 (T2) 2Za strujanje vazduha u kanalima trebapoznavati protok i napor sistema.Protok je koli~ina gasa koja proti~e ujedinici vremena kroz sistem i meri seu m 3/s ili m 3/h.
