I think I see what the quotation of the Original Poster is trying to say. I assume this is a direct quote from the source that he found the layout diagram in. That the piping configuration shown is the most efficient as it is all basically fitting-to-fitting so it reduces the piping length and...

I think that is a good arrangement for hot piping. The vertical down pipe will absorb thermal expansion difference between the hot and cold pumps more than if the common header was on the same elevation of the pumps and no vertical drops. The elbow supports would be free sliding. A piping...

Yeah looking at the head loss tables for 6", 8" and 10" 5 ft/100 feet loss is about 10 ft/sec, 13 ft/sec and 14 ft/sec, which is kind of high. I usually just stick to close to 7 ft/sec or 9 ft/sec maximum.

I think he means head loss per 100 feet of pipe like 5 ft per100 ft friction loss. That sounds about a reasonable friction loss resulting in a velocity of 7 to 10 ft/sec. I myself never used that rule of thumb but just try to maintain a velocity of 7 to 10 ft/sec. It is my understanding that...

Here is a very old Exxon spec for multiphase twin rotor PD pumps which has a little information on materials and other info that may be helpful.

5% of what? What kind of water pipe systems you are talking about?

Here is another reference on corrosion in Oil and Gas Industry.

Looks like you just have H2S in the liquid phase in 18 PPM concentrations. NACE will give recommendations on materials for different H2S concentrations. CO2 is extremely corrosive due to formation of carbonic acid in water. 10% CO2 of gas phase is an extreme amount and I believe you would not...

I agree with LI. Don't eliminate anything but in each internship mention experience directly related to the job you are applying for even if you have to be a little creative and come up with a way to link your experience with the job you are applying for. For those without a lot of related...

The OP said there are two filters in series each at normal pressure drop of 0.5 kg/cm2 or 1.0 kg/cm2 and for two in series and total of 2 kg/cm2 max. for two dirty filters in series. Therefore there will be a minimum of 10 m head available upstream of the booster pump, so booster pump needs to...

I am not sure why you say you can't apply Bernoulli. All fluids is an application of the balance of energy terms which are found in the Bernoulli equation: P1/gamma + V1^2/2g +H1 = P2/gamma + V2^2/2g +H2 + H friction The only issue I see is that once you get to where below vapor pressure is...

Stellite is a hard facing material plated onto an integral seat. An integral seat is a seat that is formed into the metal body of the valve so the seat is part of the metal block of the valve.

I should have mentioned that yes the height does cancel. In my calculations I found Hd by taking pressure Hc and subtracting the friction from c to d and the static height, however the same static height is added back from e to f. The important thing is to trace the pressure in the system and...

I checked calculations for 4 cases attached. I assumed 4 inch ID pipe at 350 gpm just for setting up a reasonable example. Based on the total friction loss of 5 bar I calculated a total line length to produce 5 bar (167.3 feet) head loss. I then broke up line into segments based on the known...

I think your resume looks impressive for someone still in college. I would gear it more to the type of job you are applying for. I would do this by wording it to highlight skills and experience that is specifically related to the job you are applying for so that it looks like your career path...
