Thanks BigInch, I see there is more questions then answers with this one, and i certainly am not the man to answer them! The investigation into such an endeavour is probably more trouble (time consuming) than its worth for me anyway. Besides construction, the simple fact of maintenance is a big...

I forgot to include in the case of the 2 in one, is it possible to lay these pipes in two separate campaigns remembering that it is more for space then savings that i would like to attempt this?

Thanks BigInch, Just on a final point, do you believe that the 2 in one is technical viable but in practice risky and unreasonable? And also, is a DP system sufficient for laying pipe, or do you need an anchor system aswell? (Especially with such large pipework)

Thanks Big Inch very informative as ever. I had thought laying such large pipelines in the same trench would be close to impossible. It is more for reasons of space that i've had to look at the option. The pipe route itself has a few large radius bends which will hamper the idea even further...

Hi all, Similar to the previous thread "2 pipelines in one trench", which was based on an onshore basis. I am working on a project where i have two 42" gas lines which i am thinking about running in the same trench over a 200km + distance. I am relatively new to the industry and thought ye...

It might be worth asking in the valve engineering forum

I am no expert in this field but if you are looking to just get this motor running for your experiment, then it is essentially a matter of checking that you are feeding the motor sufficient ampage as well as voltage. if you are unsure of which wires to connect the power, why not clip the...

Thanks Bris, I have previously viewed the above datasheets.Manning's is indeed alot easier especially with Bimr's calculator! But for the purposes of my piece of mind, i would like to continue to look at a method of solving this by colebrook white formula. I have attached my method used, from...

Thank you both for your posts, while not the cole-brook eq, i find this very helpful as a reference.

Hello, I have a question regarding a gravity flow pipe scenario. Water flows through a wide-ish channel at its end it is collected by a 798mm (ID) pipe. I have used the attached Cole-brook White formula to calculate the velocity through the pipe at full flow. I am getting a velocity of about...

I worked through your calc. Bimr and found the time to be approx. 8070 sec. If this is correct, how can there be such a difference between our answers(mine being close to 13,000 sec.). While i love a simple formula myself, i can't help but think that this leaves out some critical data such as...

Thanks for your thoughts. I have looked at the example and formula supplied by efunda (thanks Bimr), and worked the solution for a typical size tank, 10m diameter, 10m depth. I calculated for the top level and worked a table for the falling values. I think i got a bit carried away with the 1...

Hi all, I have a question which has plagued me with quiet awhile. If a tank (circular or other) has to be drained, what is the formula to calculate the total time taken to empty such a tank? Also, if the outlet of the tank was connected to the inlet of another tank at the same level (same...
