- Homework Statement
- If I convert from cfm to scfm, should I use the density of the material at standard conditions or what the conditions the material is actually at?

- Relevant Equations
- lb/hr = cubic feet/min * 60 min/hr * lb/cubic feet

For air for example at conditions 150 F and 125 psig, density is 0.61lb/ft3

At standard conditions it's 0.0765lb/ft3

If I convert 500 cfm to scfm, does this mean I should multiply by 0.0765lb/ft3*60min/hr to convert to lb/hr?

At standard conditions it's 0.0765lb/ft3
