where by vdot equals the quantity circulation price, mdot equals the mass move price in the place and v equals the particular quantity which we just calculated.
The next factor to determine is the friction decline get more info level of the ducts. Knowing the right friction decline rate might help with advertising smoother airflow.
Permit’s tackle one of the additional essential questions relevant to HVAC duct sizing. To be much more particular, let’s try out to answer why obtaining the duct size correct is so important.
