My two cents: Start looking for another job yesterday based on what you've described. The job market, in general, is excellent right now for engineers - including mechanicals. I'm not sure what industry you're aspiring to stay in or move into, but my personal opinion is that one spends WAY too...

Junaid, Your question is a common one - which I have a canned answer for: Well, it depends...what has the local jurisdiction committed to?

FWIW, many states have or are moving toward requirements that the stamping engineer observe the construction of their design for general conformance to the design requirements (the extent/scope of these observations can be somewhat contentious based upon some interpretation of various state's...

Strictly looking at the offer: that's a pretty low offer, especially to be familiar with the company, their processes, etc. I'm guessing his initial duties will be to continue what he's doing in his internship and "slowly" creep into some engineering responsibilities - I would be curious what...

It's not worth evaluating - have the subcontractor correct the misalignment at their cost.

I take it the picture is more of a schematic representation of the system? I say that because my first observation is that I'm having trouble visualizing how the balancing pipe is going to function between the underground and above ground tanks...I'm assuming it's a given there's an elevation...

I believe SparWeb hit the nail on the head: I am not in the aviation industry, but I can empathize on the point that last minute changes on a project on its way out the door often do not receive the same level of scrutiny as they would inside of the "normal" design process. It typically takes...

Based on this statement, I'm assuming there's no actual law or jurisdiction requiring the stamp aside from your client's requirement. As such, I would infer that it is completely up to your client what they will accept. Your approach seems reasonable to me given what you've stated. You could...

It appears the two sensor 23's are indeed the same sensor...one item is reporting hourly outflow, the other daily. Looking at the data, there is a comments field near the top which states in part: "Outflow from Oroville includes all releases from the Oroville Dam (i.e.: Hyatt, spillway, low...

Flexible wedge gate valves are designed to provide more positive sealing at both low and high pressure differentials - with isolation service in mind. I'm not aware of a gate valve design with a strengthened stem-to-wedge connection. I believe you'll find that most manufacturers warn against...

I would caution you against the use of a gate valve for this scenario. One likely failure scenario for a gate valve subjected to severe duty scenarios such as the one you are describing (mitigating a surge) is that the wedge separates from the stem - the wedge will then fall into the seat...

WARose, I'm not aware, as stookeyfpe has pointed out, of a hard and fast weight limit for the valve box lid. NFPA 24 simply states in section 6.4.2 that "Where used, valve pits shall be of adequate size and accessible for inspection, operation, testing, maintenance, and removal of equipment...

For 650 deg F, I agree that A193 B7 is appropriate. As BJI states, A193 B16 can be used, but will really be overkill. B7 should be good for up to about 750 deg F service temperature applications. B16 is good for up to around 1,000 deg F.

I recall an interesting paper I stumbled upon several years ago which proposed a methodology for estimating engineering effort based on material quantities and labor hours for a project - likely more suited for an EPC type of project, but I believe it fits the discussion here. Here is a Link to...

quizzical1, I believe D Scullion has certainly provided some excellent information for you. To directly answer your question based on my experience - there is no standard reference for engineering manhour estimates (as you state, each task or project will have its own nuances). In order to...

Are regular samples taken of the process fluid to track chemistry? I would expect, if nothing else, your samples would readily indicate if your pump was degraded or malfunctioning. Also agreed with tracking chemical volume in the feed container - which I also assume takes place so that you know...

Agreed with XL83NL. You can't "cherry-pick" code requirements, even to "mix them." You either meet the code, or you do not. For example, you aren't going to get an ASME stamp on the vessel by following half the code. In general for a situation as you describe, I would expect the vessel to be...

crb7, I believe you are correct. Further down in that section of NFPA 13 (2016), 7.2.3.3 states "A system size of not more than 500 gal (1900 L) shall be permitted without a quick-opening device and shall not be required to meet any specific water delivery requirement to the inspection test...

I wouldn't be surprised if this incident drives a new standard or series of standards from NFPA regarding facilities or occupancies designed exclusively for robots. Living in the future is fascinating.

Hi all, I'm currently working on a power plant project in which the condenser circulating water is taken from a set of supply wells, passed once through the condenser, then sent to a set of injection wells. Another engineering firm designed the injection wells and associated piping. The...
