1.4 Calculating Flow Rates

The most frequent ratio is 5:1. The charts above list the breakdown for many ratios and flow rates. It is useful to be able to calculate flow rates when a chart is not available.

An example of calculating the water and syrup flow rates given the finished drink flow rate and the water to syrup ratio:

Given:

1.Finished Drink Flow Rate = 3.0 oz./sec.

2.Water to Syrup Ratio = 5 to 1

To calculate Water Flow Rate:

1.Calculate the Total Portions = Water Portion + Syrup Portion (example 5 + 1 = 6)

2.Calculate Syrup Flow Rate = Finished Drink Flow Rate ÷ Total Portions (example 3.0 oz./sec ÷ 6 = .5 oz./sec)

3.Calculate Water Flow Rate = Finished Drink Flow Rate – Syrup Flow Rate (example 3.0 oz./sec - .5 oz./sec = 2.5 oz./sec)

Prove the calculation is correct by adding water flow rate of 2.5 oz./sec + syrup flow rate of .5 oz./sec = finished drink flow rate of 3.0 oz./sec.

Water flowing at 2.5 oz./sec and syrup flowing at .5 oz./sec achieves a ratio of 5:1 and 3.0 oz./sec. flow rate.
