# C153 – Totalisation – User Entered Flowrate

## Description

This calculates the total from a user entered flow rate.

## References

Kelton calculation reference C153

KIMS calculation reference K113

## Options

### Flowrates

- Volume
- Mass
- Standard Volume
- Normal Volume
- Energy

This option allows selection of the types of flow rate to be totalised.

### Enter elapsed times as

- Duration
- Start and end time

This option is used to select a method of entering the elapsed.

### 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.

## Calculation

### 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.
