mikycampo,
yes, the internal pressure has an effect in the natural frequencies of a pipe configuration, but the effect can be large or small depending of a lot of factors.
as you know the frequency depends on stiffness and mass, an
elbow is stiffened when subjected to internal pressure so the...
i want to thank dcasto(chemical)and BigInch(Petroleum) for their comments, that are very valuable to me.
Just to clarify my poor description, yes, there is a pressure control valve after the block valve of the meter on the first configuration.
What i have clear now is that the second...
my question is this:
i have two liquid metering stations both are very similar in configuration, except that one has the outlet and the inlet to/from the Prover at the very end of the station, with a block valve in between outlet and inlet branches who also has block valves. The other...
we had an argument here, we are designing an refinated products storage and distribution terminal and according
to a table of minimum distances between equipment, tanks, racks, and buildings for safety reasons, it is read that between fire pump stations and administration buildings the distance...

thanks for your comment, yes I know that can basic for MS is there and have done some macros for certain purposes, my problem is that now I have a macro that hardly fits the 64Kb MS basic program limitation. I even tried to divide it in two macros but aparently the limitation persists.
Let's assume that the vibration displacement is a pure sine <br>
x(t)=A * sin(wt), the first derivative gives the velocity<br>
of the vibration that's is :v(t)= A * w * cos(wt)<br>
So the relationship you are looking for is the rotational speed w (measured in rad/sec), the velocity amplitude V=...
I have been trying to program an aplication in Visual Basic that I want to connect with Microstation but the information that I have found doesn't help in every respect, does anyone knows where to find some information on that?
I have found very scarce information on this type of failures and in real material properties to verify designs, does anybody have information or sugestions?
