Fundamentals of Fluid Mechanics Questions and Answers  




I guess you mean A6Q3. If you can't determine velocity because not enough information is given, you'll need to assume that the kinetic energy is small. Just make sure you state your assumptions correctly.




Hint. For a liquid, $e=h=cT$ with $c$ a constant. For a liquid, the temperature can not change in time unless there is heat transfer to the liquid because the liquid is incompressible. Thus, in this case because there is no heat transfer, the temperature of the liquid will not vary.




Some terms looks off. After simplifications are done, the equation to integrate is not so different as the one I integrated in class today.




There's a mistake somewhere because this should cancel out with another term.




Not quite but.. it's something along those lines.



$\pi$
