Stopples Eq. Length
Stopples Eq. Length
(OP)
For pressure drop calculation- what would be resistance coefficient and equ. length for stopples? Would be the same as the pipe size?

Is this a joke?
Good luck,

To a ChE, the glass is always full - 1/2 air and 1/2 water.

Wrong symbols were used on the drawings! They are not stopples. I found out they are check valves not stopples but called out that way.

If are using the 3-K method, then K = (2025/Nre) + 0.621 [1 + 4.0 (25.4/ID)^0.3], where ID = pipe id in mm, Nre = piping Reynolds number. I've had to extrapolate this myself from other known info, since there is no literature for swing checks in the 3-K docs.
Pls also note there is a minimum velocity which must be exceeded for swing / dual plate checks to enable stable flow - you may glean this off the internet - but be careful to cross check this against other guidance.
