How to find flow velocity if you know mass flow rate
Thread Content
For example, if you know the mass flow rate, how to calculate the flow rate? Which formula is the most accurate? Novice learning * , please give me some advice, thank you all sea friends
Flow rate/pipe cross-sectional area = flow rate has nothing to do with mass
Flow rate (m/s) = mass flow rate (kg/h) ÷ density ρ (kg/m3) ÷ 3600 (s) ÷ (π × di × di 4) (m2)
The mass flow rate is now converted into volume flow rate, and the volume flow rate divided by the cross-sectional area of the pipe is the medium flow rate.

Reply 4# gujiaming1985 Thank you Haiyou, I took note of {:1_90:}
Flow rate = mass flow rate 4Ws/（π* d * d * Density ρ), all units in the formula are SI units, π=3.14
This is arithmetic, not chemical engineering. The appraisal is completed.
Need to know the density of the material. Flow rate = mass flow/density ρ/pipe cross-sectional area
