I'm analyzing a pipe using FEMAP and I've been having some problems how best to constrain the model. The pipe is mounted on simple supports at 7.5m spacings. I've used shell (plate) elements to model half the cross section of the pipe to take into account bending and half the section between the...
Currently there are only 2 or 4 strain gauges at the fixed end and no force gauge (which is basically a strain gauge anyway) at the tip. It's mainly to be used as a calibration device for other instruments so I'm not too fussed about determining the applied force - the main difficulty so far has...
Hi there,
I'm attempting to perform a modal test on a cantilever beam. The idea is to measure the strain at the constrained end using strain gauges, with output to a datalogger. A signal generator and shaker will provide the sinusoidal applied force at the tip. My question relates to how best...
Thanks Zekeman but I'm assuming the oil does not change temperature but stays at 10degC. I believe this is a reasonable assumption for a short section of pipe or discrete time step.
I think I have a numerical method of solving it through timesteps using a similar equation as your eqn 1. I'm...
Thanks guys. I'm thinking FE might be the best option but is there any way of simplifying the problem. Assume no insulation. I don't know how long the heating band will be so assuming 1m at the moment (i.e. pipe length = 1m).
For steady state (or time =0) I've calculated the following (mainly...
I have a bit of a tricky heat transfer problem and was wondering if someone could point me in the right direction if possible.
There is an above ground stainless steel pipeline containing crude oil @ 10degC and 130 m3/hr. The pipe has OD 508mm and thickness 6.35mm. A heating band is then...
This one has stumped me for a while and I can't seem to find an answer.
Why are commissioning sets always specified as being in the return leg of a LTHW system?
Is there a logical reason or just tradition?
Much obliged for your help :-)
