(a)
Coil width = Length in the direction of a coil header, typically vertical.
(b)
Coil width = Length in the direction of a coil header, typically vertical.
(c)
The minimum waterflow at 1-1.5 fps tubeside velocity is to ensure the coil self-vents properly. There is no minimum waterflow limit for coils that do not
require self venting. See "Water Coil Piping" section for minimum self venting velocities.
(d)
Maximum gpm limits are to prevent erosion and noise problems.
