# C203 – Flow rate Totalisation Check

## Description

This calculation is used for a totalisation check, flow rates are integrated with respect to time.

## References

Kelton calculation reference C203

## Options

### Elapsed Time

- Duration

- Start and end time

Select a method of entering the elapsed.

### Flow rates

Flow rates q can be entered for any of the following quantities

- Mass

- Observed volume

- Standard volume

- Normal volume

- Energy

### Totals

- Use start and end totals

This option is used to input 2 totals and find the incremental total between the start and end totals.

## Calculations

### Calculate the elapsed time

If start and end time is selected for the time input:

Where | ||

t_{e} |
= | The time at the end of the test |

t_{s} |
= | The time at the start of the test |

### Calculate the total

The total is calculated by multiplying the flow rate by the duration

Where | ||

t | = | Duration |

q | = | Flow rate |

Note: The units will correspond to the flow rate, for example a mass value will be returned for a mass flow rate and a volume returned for a volume flow rate.
