Thought this might be the best forum to ask for leads... I am looking for Pressure Relief or Safety Valve options for a vessel operating at 450 PSI and 750C, with pressurized syngas. The pressure does not seem to be a problem but the temperature is. Any thoughts on where I could start a search...
I've been through my Machinery's and Marks', but can't find a beam bending diagram for a beam that is loaded at 2 points, one on the cantilever end and one between two other supports, sort of like this:

I've tried for some time to figure out how to most efficiently manage my time and my work load. I'm typically involved in several projects at once, and my tasks range from overall management of the project to very small ("to-do") items. What do you all do to track the work you are currently...
Our facility was designed with sanitary sewer lines from various points which gravity-feed into a common lift station, and then pumped into a new forcemain that eventually feeds into the municipal system. A new building is being erected on site which will have washrooms, however this new...
Our new facility is being asked by the city to install flow meters on our (2) sanitary sewer lines. As of now, they have no way to measure the amount of wastewater that we pump to them for treatment. I think that an ultrasonic flow meter (Endress-Hauser Prosonic) would work well, but what we...
I have a situation that I'm not sure how to approach. I have a series of braided metal hoses through which a hot oil (~450F) flows. These hoses are uninsulated and therefore lose heat to the ambient surroundings. A pneumatic system being installed may result in a large air flow (ambient...
How effective is a ceramic coating when compared to traditional aluminum-clad mineral wool? I have no experience with the ceramic coating but from the literature I have read it seems to have excellent resistance to radiant heat but poor performance due to conductive heat transfer. Our...

I have a series of tasks that are linked. In the Gantt Chart view, I can clearly see the series of tasks starting a certain day, and the following tasks happening consecutively like I would suspect.
Now, the weird part: When I go to my Resource Usage view, I see one of my resources working on...
I know that I can export selected data from a project into a spreadsheet, but is there a way to export a report? The reports involve some calculations inside Project before they display the report (adding hours, calculating cost, etc.) and I don't want to export the raw data and have to...
I tried to set up a master project file that references several external projects. The resources are the same for all external projects. My problem is that I don't know how to make the master project file realize that these are shared resources between the projects. For example, "Resource1"...
I have an application where an existing abort stack on a wood-fired combustion unit is to be replaced by a new, taller stack. In order for the new stack to be free-standing and the correct height, the base must be much larger than the top section (60" base versus 30" top). The larger diameter...
We have started using AutoCAD 2005, but are having trouble with one of the time-saving tools that we like to use. AutoCAD 2005 uses "tool pallets", where we can store commonly used blocks and easily insert them into drawings. When a new block is drawn, it can be saved to the pallets. It's a...
I need some advice on estimating operating conditions for a fan. I have a simple exhaust system moving air through approximately 180' of 66" round duct, through a fan, and then discharging the air into a stack. I know the desired air flow, and the inlet and outlet velocity of the fan. How can...
Do any of you work in engineering offices that use a computer-based document management system? I heard a presentation on them once, and have checked out some vendor's web sites, but I wonder how practical these programs are for an engineering consulting office. I would appreciate any feedback...
I found a calculator online (http://www.hrsgdesign.com/page5_6.htm) that claims to calculate the tube wall temperature. I believe this would give me an idea of the superheater tube wall temperature, given the process steam temperature at the superheater outlet. If so, I need to know the...

Does anyone have any experience with using an evaporation process to remove water from a solution. The solution is approximately 65% water, 30% sodium silicate, and a handful of other solutes. I need to remove half of the water from the...
I am scheduled to take the Mechanical Engineering PE Exam this coming spring, and I'm hoping some of you can shed some light on how I go about studying.
I've signed up for Professional Publication's "Passing Zone" program (www.thepassingzone.com), where they give you questions and...
