All the math you ever needed to know you learned between kindergarten and 8th grade. But you probably forgot some of it! Radiator Service Co.’s David Bienvenu explains everyday product calculations and formulas that will reduce project time, increase efficiency, and help insure accuracy.

In Part 1 of “Radiator Math,” members learned about OD, ID, circumference, area and how to apply that to everyday shop situations. In Part 2 of “Radiator Math,” David Bienvenu explains how calculations are used to determine the triangular pitch of heat exchanger tubes, a fan blade angle, belt length using shaft centers, and pulley sizes or shaft centers knowing pulley sizes and belt length.

Also included are screen shots of helpful apps and excel spread sheets I’ve made to calculate fan blade angles, fan tip speed, metric conversions, drill speed and feed, heat exchanger surface area, tube weight, oil coolers BTU’s required and plate and frame tightening dimensions.

This presentation was originally part of NARSA’s Heavy Duty Heating & Cooling Conference in Buffalo, New York in 2015.
