## Mixing Ratio Formula

The following 3 formulas are used to calculate the mixing ratio of air.

MR = 6.11 X 10 ^ ( 7.5*DP/(237.7+DP))

SMR = 6.11 X 10 ^ ( 7.5*T/(237.7+T))

- Where DP is the dew point (C)
- T is the termpature
- MR is the mixing ratio
- SMR is the saturated mixing ratio

## Mixing Ratio Definitoin

A mixing ratio is defined as the ratio of the mass of water vapor in air to the mass of the dray air.

## Mixing Ratio Example

How to calculate mixing ratio?

**First, determine the dew point.**Calculate the dew point of the air.

**Next, measure the temperature.**Measure or calculate the temperature of the air.

**Finally, calculate the mixing ratio.**Use the formula above to calculate the mixing ratio.

## FAQ

**What is a mixing ratio?**

A mixing ratio is a ratio of the total mass of water vapor in air to the total mass of dry air. In other words how much water is suspended per unit of dry air.

**How is mixing ratio calculated?**

A mixing ratio is calculated using the temperature and dew point.
