Enter the concentration, flow rate, and time period into the calculator to determine the Hach Flow. This calculator helps in estimating the mass of a substance that flows through a channel over a specified time.

Hach Flow Formula

The following formula is used to calculate the Hach Flow.

HF = C * FR * TP * 3600 / 1000

Variables:

  • HF is the Hach Flow (kg)
  • C is the concentration of the substance in the water (mg/L)
  • FR is the flow rate (L/s)
  • TP is the time period over which the flow is measured (hours)

To calculate the Hach Flow, multiply the concentration of the substance by the flow rate and the time period, then convert the result to kilograms.

What is Hach Flow?

Hach Flow is a term used to describe the mass of a substance that passes through a channel or pipe over a certain period of time. It is often used in water treatment and environmental monitoring to estimate the load of pollutants or nutrients being transported in a water body. The calculation takes into account the concentration of the substance, the flow rate of the water, and the time period over which the flow is measured.

How to Calculate Hach Flow?

The following steps outline how to calculate the Hach Flow.


  1. First, determine the concentration of the substance in the water (C) in milligrams per liter (mg/L).
  2. Next, determine the flow rate (FR) in liters per second (L/s).
  3. Next, determine the time period over which the flow is measured (TP) in hours.
  4. Next, gather the formula from above = HF = C * FR * TP * 3600 / 1000.
  5. Finally, calculate the Hach Flow (HF) in kilograms.
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Concentration (C) = 200 mg/L

Flow Rate (FR) = 5 L/s

Time Period (TP) = 3 hours
