Mass flow
Convert thousand pounds per hour (klb/h) to kilogram per hour (kg/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 klb/h = 453.5924 kg/h
To convert thousand pounds per hour to kilogram per hour, multiply the klb/h value by 453.5924. To go the other way, divide by 453.5924 (or multiply by 0.002204623).
| klb/h | kg/h |
|---|---|
| 1 | 453.5924 |
| 2 | 907.1847 |
| 5 | 2267.962 |
| 10 | 4535.924 |
| 25 | 11339.81 |
| 50 | 22679.62 |
| 100 | 45359.24 |
| 250 | 113398.1 |
| 500 | 226796.2 |
| 1000 | 453592.4 |
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 22.04623 klb/h is 10000 kg/h.
Multiply the value in klb/h by 453.5924 to get kg/h. For example, 10 klb/h = 4535.924 kg/h.
1 klb/h equals 453.5924 kg/h.
Material and energy balances are written on a mass basis, so plant flows convert between kg/h, t/h, and lb/h constantly.
