How To Calculate The Powder Conveying Rate

  • Calculating the Cost of Powder Coating | Products Finishing

    Aug 01, 2017· Powder cost per pound = $3.50 ; A pound of powder with a specific gravity of 1.0 at 100-percent utilization will cover 192.3 ft. 2 at a thickness of 1 mil. That is the starting point for calculating the powder cost. 192.3 × 0.90 material utilization with reclaim ÷ 2 mils thickness × 1.4 specific gravity = ft. 2 /lb. 173 ÷ 2.8 = 61.8 ft. 2 /lb.
