We have a digester gas stream of 2,000 CFM flow rate. It has an entering temperature of about 200 deg F and we need to cool it down to about 75 deg F (125 degree delta T). How would you calculate the BTUH of heat needed to be removed from the gas? My first instinct was to apply a modified...

Yikes! Thanks for the replies everybody. Its not so much the math that I'm afraid of as it is the additional $20K to go back to school. As well as the lifestyle changes. Having to take a part time job essentially living at or near the poverty line.... again. It would be difficult as now I'm...

Hey everyone, (not sure if this post belongs here) I currently work for a major water/wastewater/environmental consulting firm. I'm doing mostly building mechanical design- HVAC/plumbing/fire protection for facilities. Its more of an industrial type application and the money is good...

Well... I managed to land the job at the other consulting firm. I am really stoked, i was starting to go into panic mode about being laid off. I feel like my head is on the guillotine (sp?) here at my current job. This will be a nice change of pace and i look forward to it. I guess i will not...

Did this person who took the PE in California have a masters or was this with Bachelors? I interviewed with another consulting firm yesterday. The interview went great. The work consists of cogeneration design, wastewater treatment facility rennovation, and also Bio-gas harvesting. And as...

HVAC consulting is dead for the time being. There is no work on the horizon. The jobs are few and far between. I want out. I am not being challenged. I feel like a sitting duck at this point. Meanwhile there are abundant Solidworks drafting/design positions that could potentially be a...

I was thinking of starting somewhere as low man on the totem-pole. I figure we all have to start somewhere. Nobody is gonna pay me 50k if i dont know my ass from a hole in the ground. I was planning on being a 'drafter' or 'entry-level designer' for the time being to get better with...

Thank you for all your responses. I'm really torn on this one... Im going to a job interview in about an hour for another consulting type position. It a big firm with offices all across the globe, if i dont get this job then i think Im going to brush up on Solidworks skills and look for an...

Well, Im not in school anymore so I don't qualify for the student version. And i cant afford to pay for full... Is there a limited version thats geared towards the "broke-ass engineer looking to change careers" demographic? Solidworks Ver.37 , "broke-ass engineer"

Can i get away with purchasing the student version of Solidworks? I was thiinking of completing the tutorials, and challenging myself to draw things that are highly complex, with intricate assemblies. Maybe compiling a portfolio to show my skills to send to potential employers. I think that...

Getting back on track here... I really enjoy drawing in Solidworks and using FEA. Its actually quite fun IMHO. I would be willing to forgoe a pay cut. Is there a significant salary difference between an HVAC mechanical designer and Solidworks designer? Im at 55k right now straight out of...

I do have my EIT certification already... maybe someone can clear this up for me. I tried contacting the board of CA regarding the experience requirement for the PE but haven't gotten any responses. There seems to be some confusion amongst my peers. Is two years of experience plus an...

Hello everyone (first time poster), I live in Sacramento, graduated two years ago (BSME) and have been working at the same HVAC consulting firm ever since doing system design, load calcs, drafting. I enjoy the work, the problem is the industry has slowed down incredibly, and we've had to...
