Estimating Centrifuge Flow Rates

Flow rate is easily estimated by timing the output flow. The time required to fill a quart jar is extrapolated to flow in gallons per hour by the equation:

Second per Quart = 900/x,   where x= gallons per hour

Example: How many seconds to fill a quart jar for 25 GPH?
900/ 25 = 36 seconds
Working from seconds:   GPH = 900/ seconds

Example: What is GPH if time to fill quart jar is 23 seconds?
900/23 = 39.13 GPH

A liter is about 5% larger than a quart.
Flow calculations are summarized in the table below:

Gallons per Hour vs Time to Fill Quart Jar

GPH Time (seconds)
50 18
40 22.5
30 30
25 36
20 45
15 60
12 75
10 90
8 112.5
5 180
