If I am correct in this line of thought then can I say the pressure of the end of the 1/4" pipe will be the same pressure as the area it is pumping into? In this instance the 1/4" tubing will be pumping into an area which is pressurised up to 11Kpsi, can I use this as the pressure for one...

I have a problem which I am working on and its been a while since I did this at uni so I am after a little guidance :) Im trying to work out what pressure will be required to flow at a specific rate through a piece of pipe, the pipe begins with an ID of approximately 1-1/2" then drops to...

looking to design and hopefully build a micro-tensile tester to test the properties of human hair. as part of my uni class I need to design the grippers involved and have a look at non contact extensiometers. Could anyone point me in the right direction with some links or books? or even...

Homework Statement http://img166.imageshack.us/img166/4254/tut5q3ue5.jpg Homework Equations The Attempt at a Solution iv had a go at this and I think I am getting it right but just looking for a bit of clarification since my lecturer isn't giving out answers, helpfull...

ok, just worked that through and I get the right magnitude for the entropy change but I don't understand why the answer is negative. my working: W = mRt\int^{2}_{1}\frac{1}{v}dv = mRt [Ln v]^{2}_{1} = 1*0.287*288*(Ln0.5 - Ln0.06) =175.253 so, \Delta S = \frac{Q}{T} =...

Homework Statement A rigid vessel of total volume 0.5m3 contains 1kg of air at 15°C initially constrained in a volume of 0.06m3 by a diaphragm. The remaining volume is completely evacuated (pressure = 0). If the diaphragm is burst, allowing free adiabatic expansion of the air, determine...

Homework Statement having my brain fried with some dynamics problems for uni and my lecturer is on holiday so I don't have anyone to ask. Currently working on un-dampened vibration and simple harmonic motion and I can work out basic questions such as a weight hanging on a spring but when it...
