ione, Steamdog, and SNORGY thanks for your information and insight it has helped tremendously.

I am very aware of the temperature differences of the two steam sources. What I'm really after is if the design properly incorporates using the 60 psig steam (equipment has been selected at the higher operating condition, i can get the required performance, pipe is selected properly, I am...

Ok so no energy is lost and the HX's are actually more efficient at the lower pressure. Are there any additional installation considerations that need to be made because I am using the 60 psig steam? ASME ratings, service issues, etc. None of my literature addresses any of that.

I am working on a system and I have 60 psig steam available. All of my components, HX's, coils, etc can be operated at this higher pressure. However, my previous experience (every steam system I have come across the steam was transported at a higher pressure and used at a lower pressure) and...

jraef, your are dead right a swag is a swag which is why I was attempting to get additional information to set a baseline worst case. Unfortunately there just isn't enough information on the motor to even try and get performance data from a manufacturer. Also, due to the nature of the motor's...

You all have pretty much confirmed that without test or factory data it's a shot in the dark. I was glad to see that my initial shot was in-line with your responses. I was pegging it at somewhere between 80-90%. Thanks for all the info.

I am trying to figure out the heat load in a municipal pumping station. The dominating load is three 4160 volt motors, dating from the mid 80's, driving the pumps. I have been trying to determine the standard or baseline efficiencies for motors of this type from this time and can't find diddly...

Ron, He indicated that he was already taking into account vacation and holidays into the billing rate. 40*52 = 2080 hrs 2-Weeks Vacation - 80 hrs 7 Paid Holidays - 56 hrs 1944 hrs available to bill in the year 5 days training - 40 hours 1-(40/1944) = 97.9% I did muck up the phrasing...

waytsh If you have the work for them to do, their billable time should approach 100%. Any substantial deviation from that should be due to lack of work or important support tasks. An employee at that level is dependent on you to provide them their tasks and workload. I would expect that any...

Like others here our entire company (small 12 person consulting firm) took a pay-cut along with a reduced work week when our business slowed substantially. This decision was made among the 'senior' staff (PEs and PMs). We have now returned to a normal, plus some, work schedule and it was the...

I just double checked a Design Cooling Capacities report from a project I previously ran in Trace and it does not list a time for the Peak Plant Loads only for the Block Plant Loads. The only obvious error from your description is that Trace has assigned a time to your peak load. By its...

It depends on the AHJ whether or not sealed as-built drawings are required. That should always be addressed on the front end of a project. If you were to issue the as-built drawings with the engineer's stamp and company information without the engineer actually being involved you could be...

Acknowledge your mistake and be proactive about fixing it. Don't shy away from it. When the boss gets back tell him, X went out, Y was wrong, we did Z and all is good in the world. (As others have stated this should be fairly easy if it's just a border.) Part of being a good engineer is...

You are correct MintJulep. But apparently there is some discrepency as to when the elevator code changed and became enforcable. I did some further investigating and what I have concluded is I have two departments that are completely seperate (one state, one local) that both have elevator sump...

Interesting ajack1 have you had to, or better yet chosen to, impose your penalty. I don't know of many people that actually enforce the penalty clauses in their invoices. But with your generous terms I think I would always apply the penalty no exceptions. The alternative is a quickpay...

MintJulep thanks for the input. Unfortunately the system has already been designed and installed and has been through option 2 which brings me back to option 1. Apparently this requirement is brand new and the elevator inspectors are just starting (it is a point of emphasis, stealing from this...

I'm not sure if this is the right forum, but this one gets lots of eyes so I'll give it a shot. I just got surprised on a project with a 55 GPM per elevator sump pump requirement. This apparently originates from ANSI A17.1 Elevator code. I have 3 elevators sharing a pump so according to this...

It may, but do you really want to do your work for free? Do you want to tie up huge chunks of your time (& money) to work on project(s) that you won't get paid for? I hate to sterotype but architects can be the worst when it comes to using consultants as banks. (Developers are a close second...

ypwtb I have a couple of things I will throw out. 1st off are you sure it is a 15A outlet and not a 20A outlet and its 115 and not 120? I did some quick math and the Trane catalog is consistant between the three voltages. They are carrying 2597.5 Watts for the receptacle. If you assume a...

Someone somewhere in your company felt that your position needed filled and that you were the right person for the job. In this economic climate there are not a lot of firms that can bring people on to not have them be productive. Maybe they brought you on for a project on the horizon, maybe...
