FAQs on Mass Flow Rate of under flow

What is the formula to find Mass Flow Rate of under flow?
The formula of Mass Flow Rate of under flow is expressed as Mass Flow Rate of Underflow = Mass Flow Rate of Feed*((Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Feed)/(Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Underflow)). Here is an example- 10 = 20*((0.3-0.2)/(0.3-0.1)).
How to calculate Mass Flow Rate of under flow?
With Mass Flow Rate of Feed (F), Mass Fraction of Material A in Overflow (XD), Mass Fraction of Material A in Feed (XF) & Mass Fraction of Material A in Underflow (XB) we can find Mass Flow Rate of under flow using the formula - Mass Flow Rate of Underflow = Mass Flow Rate of Feed*((Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Feed)/(Mass Fraction of Material A in Overflow-Mass Fraction of Material A in Underflow)).
Can the Mass Flow Rate of under flow be negative?
No, the Mass Flow Rate of under flow, measured in Mass Flow Rate cannot be negative.
Which unit is used to measure Mass Flow Rate of under flow?
Mass Flow Rate of under flow is usually measured using the Kilogram per Second[kg/s] for Mass Flow Rate. Gram per Second[kg/s], Gram per Hour[kg/s], Milligram per Minute[kg/s] are the few other units in which Mass Flow Rate of under flow can be measured.
