Help with transient mass balance for desalination by destillation

AI Thread Summary
The discussion focuses on solving a transient mass balance equation for a desalination process using distillation. The user has derived an equation involving the density and volume of the fluid but is seeking clarification on a specific term related to mass inflow and densities. There is confusion regarding the derivation of the term rhob*Min*(1-n)/(rhos + rhow). The conversation emphasizes the importance of understanding the mass balance in the context of desalination. Clarification on this term is crucial for progressing in the homework problem.

The Attempt at a Solution



So far I have gotten:
d[rhob*V]/dt = Min - ?
 
Physics news on Phys.org
d[rhob*V]/dt = Min - rhob*Min*(1-n)/(rhos + rhow)

is what i got
 
Mind me asking how you got the out term (the rhob*Min*(1-n)/(rhos + rhow))? Not saying that you are wrong but having trouble getting this and curious how you got to that.
