Fundamentals of Fluid Mechanics Questions and Answers  


You can't apply the chain rule here. You can only apply the chain rule when converting a total derivative, not a partial derivative.






You can find $q$ as a function of $\theta$ on the bump by setting $\psi$ to a constant which is determined from $r=\infty,y=h$.




Hm, OK. It will be due Tuesday after the Thanksgiving. Note that you will have two homeworks due on that week.




But, can you prove that the force has no component in $\vec{j}$? This is easier to do and will guide you towards the right solution to find the component along $\vec{i}$.




That's right. It has been corrected.
