Just incorporate during the letters to separate rows then declare what style of fitting or duct that corresponds to.
The horizontal traces are for quantity circulation amount. The downward diagonal strains are for velocity, the upward diagonal traces are for duct diameter.
Jet diffusers can toss air up to twenty meters. All over again, it’s not comfortable if we permit excessive air to blast at one particular spot.
