sheave sizing
(OP)
I have some fans at work whose drives were down sized back in the 1980`s I assume for energy savings.I have original engineered specs for the systems which gives me the:
motor hp,fan rpm,cfm,static pressure( though I don`t know where it was measured),and the original driven sheave diameter.How do I calculate the motor sheave diameter and horse power or break hose power required? Thanks,tombro

RE: sheave sizing
Motor sheave diameter = fan sheave diameter x fan rpm/motor rpm
