laminar flow in a pipe will get its maximum velocity in the very center of the pipe. the profile is a parabola. U function of the radial position U=U(r); Radius = R; U(0)=Umax and U(R)=0 u(r)=Umax*(1-r**2/R**2) Umoy is indeed equal two the half of Umax. do you need more info about how to get...

I have not found anything :D - originally experimenting stirling engines (basically making pressure, temperature measurements from a stirling engine installed on an electrical heater). Not that I have worked on this for a long time but a good way I found to improve efficiency of this stirling...

if you take this backward: you use a fluid with a higher boiling point in HP#1 than in HP#2. then you always have T1>T2, so heat can keep moving. so you can connect Condenser#1 to Evaporator#2 and still have the system working.

Yes I understood that but I am basically wondering what would happen if you are cooling the first condenser with the second flask evaporator. then you cool down the second condenser with a heat sink. the way I understood this paper was that the second heat pipe fluid would boil at a higher...

second part of the abstract here: http://www.imeko.org/publications/tc12-2004/PTC12-2004-PL-003.pdf I think I just don't get it, maybe you can help me

right, but what is actually happening in the experiment with coupled heat pipes?

Hello guys, Introduction: I would like to get some input about some kind of temperature amplifier. What I have, is: - an electrical heater (basically a resistor that is heating a square piece (20x20 mm, 50-100 W) of copper). It's insulated on 5 sides of the copper cube. Only one side is...
