Use LATEX when typesetting mathematics. It's not v*v but $v\cdot v$. It's not q^2 but $q^2$. Retype your question using LATEX and I will answer it below.




This can not be assumed. If you want to make such statement, it needs to be proven.




OK. The assignment will be due on Tuesday the 25th at 11:00 am.




No, I will make an announcement soon on the D2L.




If you can integrate analytically your equation then do so. If you decide to neglect a term, then you need to justify your assumptions.






This will probably work in this case but is dangerous in the general case. The correct way is to start with the strain rates in the tables and obtain the shear stresses from the strain rates. Explain how to do that, and list the assumptions.




Whether you use the friction factor in the tables or not, you should reach the same answer. Also, your answer is definitely not correct. I see at least three fundamental mistakes in your logic.




When solving part (a) you can simply state that $dP/dx$ is a constant for fullydeveloped flow. Then, you can obtain $P=P(x,y)$. But subsequently, you'll need to demonstrate why this is.
