Mass flow
Convert kilogram per second (kg/s) to tonne per hour (t/h). Mass flow rate is the mass passing a point per unit time — the conserved quantity in a material balance, independent of temperature and pressure.
1 kg/s = 3.6 t/h
To convert kilogram per second to tonne per hour, multiply the kg/s value by 3.6. To go the other way, divide by 3.6 (or multiply by 0.2777778).
| kg/s | t/h |
|---|---|
| 1 | 3.6 |
| 2 | 7.2 |
| 5 | 18 |
| 10 | 36 |
| 25 | 90 |
| 50 | 180 |
| 100 | 360 |
| 250 | 900 |
| 500 | 1800 |
| 1000 | 3600 |
Material and energy balances are written on a mass basis, so plant flows convert between kg/h, t/h, and lb/h constantly.
Relief loads and heat duties depend on mass flow, not volumetric flow — keep the two straight when a stream's density changes.
Worked example. A mass flow rate of 2.777778 kg/s is 10 t/h.
Multiply the value in kg/s by 3.6 to get t/h. For example, 10 kg/s = 36 t/h.
1 kg/s equals 3.6 t/h.
Material and energy balances are written on a mass basis, so plant flows convert between kg/h, t/h, and lb/h constantly.
