There is no where to empty the tank unless I rent something to put at the dock end.

Welding a 4" WOL on a std wt 10" live fuel line. The fuel is gasoline. This line runs from a tank farm some miles away to a port. We are sure the line is completely purged of all air. It would be very difficult to have any flow during the operation. Must there be a minimum flow to weld...

I am looking for technical literature on in-tank pneumatic blending of fuel oil with a cutter stock to achieve a lower viscosity product. Several people in the local market say “no problem, get a compressor, install an air spider in the bottom of the tank, and let her rip.” And, “we do this all...

where do you need this tank designed? What country? That might help is connect you with the right engineer.

Ladies and Gentlemen, I don’t do heat transfer very often so I thought I post my problem and make sure I’m handling this correctly. I need to heat asphalt in a tank using pipe coils circulating hot oil. The tank will be agitated and the one-day temperature change would be 307-F to 310-F or...

This is an owner / operator preference. I would think (4) would be typical. No less than three.

I’ve never heard of a code required size or a special formula. 650 certainly doesn’t have one. I think you just use common sense considering: 1) the expected flow rate, 2) the frequency of use, and 3) the amount of water expected (in the case of a water bottom collection.) The expected flow...

Thank you all for you input. However, these suggestion appear to be text books aimed at students. I'm really looking for a reference book for a field engineer that would have tables of heat transfer coefficients for various real-world applications. For example, heat loss in buried pipes, heat...

I would think for vessell capacity calculations you would strap the outside and deduct the plate thickness. Strapping the outside is much easier than the inside. Maybe i'm missing something in your post?

Can anybody please recommend an practical book on heat transfer. Heat transfer is generally outside my field but once in a while I get involved in a heat transfer problems. I'm most interested in heat losses through vessels, pipe lines, and tank coils. I'm looking for practical information...

Well, for a given flowrate, bosting the suction pressure via a booster pump would lower the power consumption of the primary pump, but not the efficiency. However, the booster would likely consuem more than the power saved from the primary pump.

Where is the project? US or india? If US, where?

what is the fluid?

Excellent answer Trashcanman. A star for you!

I'm a little confused. Does the tank have an eliptical cross section? Or is it a round tank with an eliptical head? There are companies that specialize im manufacturing heads. The heads are probably standard ASME shapes and the manufacturers can give you the volume. Try B&W heads in Alabama.
