Hey,
a very quick question.
When you have a straight duct going out from an Exhaust Fan. Do you consider pressure loss at the branches that are feeding to the main line. ( index run)
if there is a grill at the duct run, do you consider any pressure loss for it?
please,
Hi,
In a Chilled water system, how do you calculate your head? ( what are the different types of head)
- The building is 150 meters high. Does that go in for the head caluclation?
Another question, if the pump is switched off, system full of water, what would be the reading on the gauge before...
