Swirl diffusers have angled blades to “swirl” the supply air. They may be possibly round or sq. in shape.

Around the chart we start by drawing a line from 0.sixty five pa/m the many way up after which you can draw a line across from our essential volume stream price, In cases like this for segment C we need 0.21m3/s. At this intersection we attract a line to find the velocity and we can see that it falls within the lines of 3 and 4m/s so we must estimate the value, In cases like this it is apparently about website 3.

We know each of the values for this so we will determine the mass flow level (what number of kilograms for each 2nd of air needs to enter the room). If we think about the calculation for area one, we see it calls for 0.26 kg/s. So we just repeat that calculation For the remainder of the area to find all of the mass flow fees.
