API661, Air cooler: the radial clearance between the fan tip and the fan orifice ring
API661, Air cooler: the radial clearance between the fan tip and the fan orifice ring
(OP)
API661, Clause 7.2.3.6: The radial clearance between the fan tip and the fan orifice ring shall be as shown in Table 6. I'm wondering this "radial clearance" is fan ring ID minus fan tip OD or (fan ring ID minus fan tip OD)/2?
can someone shed light on this?...many thanks
