Please write out and explain thank you :D

Two very long parallel plates of length 2L are l separated at distance B. The upper plate moves downward at a constant rate V. A fluid fills the space between the plates. Fluid is squeezed out between plates. Determine the mass flow rate and maximum velocity under the following condition: L_ _.] | a) The exit velocity is uniform. X b) The exit velocity is parabolic. 2L A mixing chamber was designed to mix three reagents from the incoming flow and tested for the mixing efficiency by measuring fluid density through the evenly split branches at the same size. Assume the three incoming fluid has density of p1, p2, pa, with controlled flow rate Q4, Q2, Q3. What would be the fluid density after mixing in ideal mixing situation
