					Hi, 
I am doing hydraulic calculation by using number of tee branch/tee straight from isometric drawing. However, I am not sure about flow through normally no flow line e.g. branch to drain line, inlet of PSV, line with NC/LC valves, bypass line of control valve.
My question is that I have to count tee straight for flow through normally no flow line or not.
Thank you very much in advance.

A straight flow through a tee is still affected by the tee even if the branch is not flowing. Decide how precise and detailed you want your calculations to be.

If the information is available, then I'd add it. As Pilesar said, straight flow tee does have an effect in fluid flow even if the branch is closed off.

					Thanks both of you for advice. I decided to input the normally no flow line.
