"WebDec 14, 2013 · from here: to here: To do that, we’re going to start with the humble piping tee and a concept known as the “Tee Law.”. The Tee Law simply states that what goes in the opening (s) of the tee must come out the remaining opening (s). In other words, if you’ve got 150 GPM going into the tee, you’re going to have 150 GPM exiting the tee. " - Chw loop
