Q) In a production line fluid C is produced. When the bottle comes under the filling heads, fluid A and fluid B are poured into it from separate tanks through two separate tubes.
The final product contains fluid A and fluid B are in a ratio of 1:4 by volume.
Once the bottle is underneath the filling heads, both liquids are filled in exactly the same time so that the bottle can move down the line for sealing and capping and another bottle can be filled up.
a) If the diameter of the fluid A tube is double that of the fluid B
tube, what is the ratio of the velocity of the fluid A: fluid B in their tubes?
b) What is the ratio of the mass flow rate of fluid A: fluid B in their tubes?
heres my working and i think i got the first part right but not sure how to do the second part.
