If we look at the calculation for space one, we see it needs 0.26 kg/s. So we just repeat that calculation For the remainder of the room to search out many of the mass flow costs.
6m/s so we increase that to the chart. Then we draw One more line on one other diagonal grid to discover our duct diameter which In cases like this is about 0.27m and we’ll incorporate that towards the desk far too.
