4.4.5.7 Capacity Losses
Long line lengths can result in a reduction in capacity
due to vapor line pressure drop and heat gain or loss.
Refer to Table 2 for capacity loss multipliers for vari-
ous vapor line diameters and lengths. Only use vapor
lines listed in Table 2 to assure proper oil return. This
table does not account for any capacity loss due to
heat gain or loss from the environment. It is extremely
important not to oversize the vapor line to minimize
capacity loss at the expense of proper oil return. If the
