The 8 × 32-in³ cylinders in a positive displacement meter assembly are rotating at a rate of 570 revolutions an hour. What is the average flow rate per min?

Step-by-Step
The 'Blue Check Mark' means that this solution was answered by an expert.

8 × 32/rev × 570 rev = 145,920 in³/h

Flow rate = 145,920/231 gal/h = 631.7 gal/h = 631.7/60 gpm = 10.53 gpm
