**Long Post** 1. Homework Statement The Mazda MX5 (2001-2005) comes with two engine sizes, 1.6 litre and 1.8 litre which are rated as 110 bhp and 146 bhp respectively at 6,500 rpm. You are required to choose one of the two engine sizes and analyse the system with a view to improving the power...

Thank you both. Excellent help.

Yeah I added fins and it made it work nicely. I'll post the whole solution that I got up soon. Unfortunately I only had a week to do this project alongside other uni committments. Not my finest hour of thermodynamics I'll admit.

Im currently writing a lab report on combined bending and torsion and comparing yield points to theory. I'm not quite sure I know what is going on though. I understnad what Tresca and Von Mises is but I'm not sure how they apply. If I were to use the equations and obtain a value over 1 for each...

Square pipe allows for larger surface area to volume ratio. This was a liquid to gas exchanger.

Inlet temperature of the air (cold fluid) that is.

Ok so my solution came out as 220 pipes in 2 separate "cores". pipes were of dimensions 20mmx2mm (rectangular) and 350mm long with 0.5mm wall thickness. Each pipe had 400 uniform flat fins, 200 per side that extended out 2mm with thickness 0.5mm. Turns out without the fins at an inlet...

Ok this is a great start thanks guys. Any suggestions for how I can best approach this problem?

Hello, I have to design a heat exchanger for my uni course and am a little stuck with where to start. I know a little about LMTD and OHTC etc etc. my main starting problem is finding material properties for ethylene glycol, I have tried Engineering Toolbox but for the maximum temperatures I am...

I was told to introduce myself first so here I am. I do Mechanical Engineering if you must know. :)
