Hi,
I have to give a one-hour brown-bag lunch training on water hammer (just the very basics!)
I am looking for some pics to illustrate the consequences of water hammer.
I wonder if anyone can kindly point out where to find or send me some photos with pipe/support failure due to surge.
Thank...
Hi,
In a stock pump manufacturers'curve two capacities and corresponding TDH are indicated: The rated one for stock (5675 USGPM @ 73.5ft)and the "equal water rating" (5900 GPM @77 ft).
The fluid is unbleached kraft with 3.5% consistency.
Nevertheless, from Gould pumps' "centrifugal pump...
Hi,
I have a 32" slurry pipe inside a tunnel (2500 m length). The pipe is straight and is anchored in 5 points, evenly distributed. At both end of the tunnel the pipe bends and then get underground.
The weight of the pipe is 600 kg / m
The weight of the internal fluid is...
Hi,
I've a copy of the British Code BS7159:1989 for design of GRP piping system. In point 7.3.4.2 it dictates for the longitudinal pressure stress the folowing equation:
Long. pressure stress = p (Di+t)/40t
where
p : internal design pressure
Di : internal diameter...
Hi,
I' m checking the stress analysis of a 28" GRP buried pipe with weld joints.
Does CAESAR II considers the thrust restraints due to internal pressure at changes of direction?
Should I provide thrust blocks at all bends ans tees ??

Hi,
I'm checking the stress analysis of a 12" stainless steel pipe, but I can´t find the allowable stress in the B31.3 code ( material ASTM 778 Gr. TP 316L)

Hi,
I'm performing a stress analysis for the recirculating piping system of an existing waste heat boiler, in CAESAR II.
From the discharge nozzle of a booster pumps to the 6" inlet headers, and from the outlet headers to the steam drum.
As a bondery condition I take the displacements of...
