In wich cases is a footer needed below ring wall??
My ground is stable rock at a depth of about 1.5m and what the civil contractor is suggesting to do, is to level the foundation up to 1.2m with concrete mixed with pieces of rock(without reinforcement) and build a foundation on top of it :1,2m...
My mistake,
I used the total Weight (Wshell+Wroof resting on shell+Wliquid projected vertically on the crw+ Wringwall) which I calculated to compare it with allowable foundation pressure under the crw.
And:
Wshell+Wroof=768Kg/m+137.3Kg/m=905.3Kg/m=609lbs/ft
H=39,37ft
h=3,93ft
q=61,5lbs/cuft(fuel...
Mr SlideRuleEra & BigInch,
Please correct me if I am wrong:
Calculating "W"(W=4310lbs/ft) shell&roof plates weight, and using "I.E.Boberg equation" for a ring wall height of 3,6ft I get the thickness for my concrete wall ring "T".(T=20in)
Also calculating Horiz. Pressure "P" on ring (again as...
Quark I can't find "Predict Storage Tank Heat Transfer Precisely by Jimmy Kumana et al appeared in Chemical Engineering March, 1982 issue", is there a link to download or buy this article?
Thanks again for your helping knowlege!
"The ring width centerline is offset radially to the tank wall as necessary to ensure that the soil bearing below is constant and not the result of any eccentric load."
Hello again BigInch,
So if I understood well do you suggest to offset the ring wall to a larger ID and rest the tank inside...
Thanks a lot everyone!!!
I thing using the formula Q=m*c*dt as quark has mentioned above gives me a clearer view...
You need 40oC in the tank and 60oC for transfer piping for what exactly product?
Ours is RMG 380(ISO 8217) whith a visc of 380cSt/50oC-pour point 30oC or RME 180...
Which is the best method for a tank foundation(D=11,46m/H=12m) made with a concrete ring wall:
A)Design the concrete ring wall, as described in API 650 Apendix B.4.2,where the centerline diameter of the ring wall is equal to the nominal diameter of the tank??
Or
B)Design the concrete ring...
Thank you for your advice!!
Parameters such as BigInch mentioned above help to get a litle bit more into heating details.
I am not looking for free consultancy service.I am just trying to clear some things out, such as the fact that my engineer is suggesting a 2.000.000kcal/h heater...
We are in the design procces of an AST for fuel oil (380cSt)for vessel bunkering supply.
Because we are not familiar with heat transfered products such as heavy fuels can anyone help how to size the capacity of the heater needed to pump the product from tank to ship??
Tank: 11,46m diam./12m...
