Mass flow rate measures how much mass passes through a point per unit of time. It is essential in chemical engineering, HVAC, and fluid mechanics.
All conversions use kg/s as the base unit.
Metric conversions:
- 1 kg/s = 1,000 g/s = 3,600 kg/h = 3.6 tonne/h
Imperial conversions:
- 1 kg/s = 2.20462 lb/s = 7,936.64 lb/h
- 1 lb/s = 0.453592 kg/s
Cross-system:
- 1 tonne/h = 2,204.62 lb/h
- 1 lb/h = 0.000126 kg/s
Common applications:
| Application | Typical Flow |
|---|---|
| Household faucet | ~0.1 kg/s |
| Fire hose | ~10 kg/s |
| Industrial boiler | 1–50 tonne/h |
| Gas turbine (air) | 50–500 kg/s |
| Oil pipeline | 100–5000 tonne/h |
