RLM2000, You should treat Mom & Pop just like the big boys, and tell them that meetings cost money and how much. We tend to limit the number of meetings in our proposals and if they want more meetings it is at additional cost. I find clients usually want to have less meetings if they know...

RLM2000, Our firm tracks our hours to perform different types of work. We use our historical record to help us establish the estimate for the work. We mostly give an estimate-not-to-exceed, and we write a scope of work with our proposal so that if there are changes to the scope of work we can...

Enpen, I have run into this issue in NJ as well. The agencies people sometimes seem to ignore the NJ Lic. Board Rules at their convience, from time to time. It depends who is involved with the project. In an effort to keep good client relations, I would try to speak with a PE in the agency...

If the water is not circulated during the standby state, then there may not be sufficient passivation taking place on the unit metal surface. Or debris can be settling on the surface, which will inhibit passivation. Heating can accelerate corrosion and stagnent seawater is not good either...

On shutdowns, we minimized the loss time by having the shift supervisors get to site on time, and chase down the safety officer authized to write WP's. This was the first item of business when the super arrived on site. Since no one worked until the permits were issued, the shift supervisor...

A very good coating system is Placite 7122 LAR or Placite 7122 HAR for seawater service. However further understanding of the application is needed. PU is used in some areas with success but it has it's limitationa and problems

Well the matter you are describing requires some study. However, generally the displaced air during filling is vented and the new air is introduced during discharge from the tank. This is a typical problem with most of the above ground storage tanks (AST). To make the processes more...

wynn, all of the above responses are very good. I agree that welding, brazing and any hot work will damage the coating. We recently were working with a client who circumvented the issue by selecting aluminum sheet. They discovered the cost was less than the mill galvanized sheet and they were...

If you reference "CAMERON HYDRAULIC DATA" the flow through orifices, nozzles and venturi tubes is provided. In your case you will have to assume the value H = difference in head between upstream end and throat in feet. This should give a good approximation, from the max to the min...

I agree with rbcoulter that the K value is needed for all the branches for distribution. If it is possible you may want to consider using a portable flow meter that would allow you to establish branch flows in a proportional basis. Another approach would be to measure pressure in each branch...

I found several articles that suggest fuel cells will cost $3500/Kw to $4200/Kw. Thanks for you help.

Does anyone know if the PEM by H Power Corp, fuel cell in Yellowstone National Park is up an running? Read September 2002 Input/Output Mechanical Engineering for some background information and information about the fuel cell application.

There are several charts from manufacturers of expansion joints listed in their catalogs. One in my bookcase is a chart from -200 F to 1400 F from Power Pipe Supports, Inc. However the chart I find most handy and use the most is in the Pressure Vessel Handbook published by Pressure Vessel...

Ouch, the low cost budget question. Well, first why do you measure the gait? I would forget about computer technology or high speed cameras. You can try digital photos or still photos on a measured out grid. You can try having the RATS run through a marker (paint) and then across paper...

Does anyone know of Pneumatic Conveying Software for the design of dilute phase and dense phase conveying systems? Thanks

Thanks for the responses. Item 2 was considered and rejected by the museum, they felt that the ICCP system would have to be maintained at a cost. Item 1 was rejected for the reasons that CoryPad gave, no strong galvanic cell to offer protection. I think you need 650 Mv potential for...

CoryPad, Yes we want the colors to show. No coatings are allowed. The museum says no coating. Any other suggestions?

We want to place a rare piece of carbon steel as a monument outside in a courtyard. The steel is A36 with a thickness of 1 inch, height of 9 inches and a length of 18 inches. This object is to be on display outside in the elements, we do not want to put an enclosure around it, such as a...

I would recommend performing a pile test. It will determine the capacity of the pile that was installed. If you can find the pile test report, then that will provide you with the answers you are looking for. The report will say that the pile was driven to say, 10 Ton capacity. Lacking that...
