Mass flow
Convert kilogram per second (kg/s) to pound per hour (lb/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 = 7936.641 lb/h
To convert kilogram per second to pound per hour, multiply the kg/s value by 7936.641. To go the other way, divide by 7936.641 (or multiply by 0.0001259979).
| kg/s | lb/h |
|---|---|
| 1 | 7936.641 |
| 2 | 15873.28 |
| 5 | 39683.21 |
| 10 | 79366.41 |
| 25 | 198416 |
| 50 | 396832.1 |
| 100 | 793664.1 |
| 250 | 1984160 |
| 500 | 3968321 |
| 1000 | 7936641 |
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 22046.23 lb/h.
Multiply the value in kg/s by 7936.641 to get lb/h. For example, 10 kg/s = 79366.41 lb/h.
1 kg/s equals 7936.641 lb/h.
Material and energy balances are written on a mass basis, so plant flows convert between kg/h, t/h, and lb/h constantly.
