Hi,
I am wondering if I can perform a transient state heat transfer analysis with Pro/Mechanica, for a storage tank filled with oil? The initial temperature of the fluid is -22C and the final temperature is 5C. The wind velocity outside the tank is 14m/s(forced convection).The heating of the...

Hi,
I have to model a NPS 48" buried pipe at 1 meter depth in soil(semi-infinite solid)K=1.7 W/ms).I need this geometry model in order to perform a steady state heat transfer analysis.The fluid inside the pipe is stationary and its temperature is 40C.
Is there anyone who could give me some...
Hi
I am doing heat transfer calculations for a 71'-0" height and 250'-0" diameter oil storage tank.The tank is not insulated and the roof of the tank is a floating type one that moves up and down with the level of the fluid in the tank. The peak velocity of the air outside the tank is 14 m/s...
Hi,
I am trying to calculate the heat transfer rate from a burried pipe(depth=1meter, length=1000meters,high viscosity crude oil) when the surface ground temperature is -35C and
-22C.The fluid is stationary and its temperature is 5C.
There is a natural convection inside the pipe, a conduction...
Hi,
I am wondering if someone knows about the Glycol Heat Tracing Systems? I need to find the number of tubes and the size of them for 24",12" 30" NPS? Any idea about a refernce manual or a handbook that would show the design procedures?

Does anyone know where could I find some comprehensive information(handbooks,tutorials, worked examples), regarding the sizing of Glycol Heat Tracing(Oil Industry?
I need the Glycol Heat Tracing Design procedure for NPS 24",12" 30" pipes.

Hi,
1)Can anybody supply me with the chemical composition and mechanical properties(Min Yield Strength for ASTM SA-350 Grade LF6 Class 1 and Class 2?
2)Can anybody supply me with the chemical composition for ASTM SA 358 309H,Gr.2.,ASTM SA 694,ASTM SA 242(Welding)
and ASTM SA 381? I also need...
Hi,
I was asked to review some data about the Maximum Unsupported Pipe Length(Feet). The data that I was given is a 12 and 16 inches diameter pipe. For a 0.250 wall thickness I was given the following lengths: 80 feet for the 12 inches diameter and 83 feet for the 16 inches diameter.The Pipe...
Hi,
I need some help with the following problem:
Given Data
StorageTank(Shell Height=59'-4")and(E=29,000000psi)and the fluid to be stored is Oil.
The Shell Body is divided in 6 Rings.(Butt Welded)..
The first ring has 117.25 inches, and the other 5 Rings have the same width (118.25 inches)...
I haverecently performed a FEA on a 100 mmm long cantilevered beam with a rectangular cross-section(Width 10mm and Height 20 mm). A load of 10N was applied downward at the free-end and the constraint was applied on the other end(fixed surface).The material was A2014.
I have used this model in...
Hi All,
I am quite new in the FEA. I would like to know what is the Von Mises stress and how is it used to predict failure?
What kind of failure is this, and what failure theory is being used?
What are the advantages/disadvantages and limitations of this theory?
Best regards,

Why the 90 degrees short-radius elbows create a larger pressure drop inside the line, then the 90 degrees long-radius elbows?Could this be illustated by a mathematical equation?
Is there any difference in pressure drops between the 45 degrees elbows and the 90 degrees long-radius elbows?
