Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I've been studying fluid mechanics for my mech. engineering degree for the past few months. Unlike my other subjects (mechanical analysis, thermodynamics, automated systems, mechanical vibrations), I can't seem to grasp the problem-solving technique.

The annoying thing is, I find the subject extremely interesting and can see how useful it is to know, and would love to be able to solve fluids problems.

I have missed quite a few lectures due to illness which could be part of the reason, but I've missed them in the other subjects too and was able to teach myself for them, but not for fluid mechanics.

I just can't seem to see the structure to solving these problems, all solutions I see seem so different and are very intimidating. I'm sure once you get over the fact that so many variables are used it probably is a lot easier than it seems, but I can't seem to do that.

Any tips on how to approach problems in fluid mechanics? I know there's a huge range of problems, but if anyone can share a general approach, or NB equations to know, or where to start with a problem.

I have an exam on Monday and really think I'm going to fail after studying hours per day for the past few months, getting literally nowhere. Any tips that will help me at least pass the exam, ways to get SOME marks at least.

Here's a sample exam paper so you know the types of questions I'm talking about.

Cheers!
