This should be simple one - but have no formula book.
I have a pipe sticking out of the ground that has been pushed down with a excavator bucket to align with the adjoining pipe.
i want to do a simple calc based on a cantilever beam (but with a pipe fixed in) to find the max deflection...
A quick heads up on Hydrotest. Looking for any approved methods that have test time <24hrs duration, suitable for large diameter onshore pipelines (test section length max 4km). Refs for standards or company approved methods would be usefull. Thanks.
80% of pipeline is backfilled, remaining 20% is exposed. we use weighted values for start and end temps to give us overall DT that is used for allowable DP for the overall DT in the Shell Depp formula.
On all previous tests, as normal we see a pressure drop when temperature drops and calculate...
The Darcy - weisbach formula is a linear pressure drop relationship, how can this be used to determine pressure drop in turbulent compressible flows. It is known that the rate of pressure drop is much greater as the gas travels downstream as compared the rate of drop when it is at relatively...
