Mass flow
Convert pound per hour (lb/h) 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 lb/h = 0.0004535924 t/h
To convert pound per hour to tonne per hour, multiply the lb/h value by 0.0004535924. To go the other way, divide by 0.0004535924 (or multiply by 2204.623).
| lb/h | t/h |
|---|---|
| 1 | 0.0004535924 |
| 2 | 0.0009071847 |
| 5 | 0.002267962 |
| 10 | 0.004535924 |
| 25 | 0.01133981 |
| 50 | 0.02267962 |
| 100 | 0.04535924 |
| 250 | 0.1133981 |
| 500 | 0.2267962 |
| 1000 | 0.4535924 |
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 22046.23 lb/h is 10 t/h.
Multiply the value in lb/h by 0.0004535924 to get t/h. For example, 10 lb/h = 0.004535924 t/h.
1 lb/h equals 0.0004535924 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.
