Hi,
I need some help/advise on how to obtain the heat generated from various equipment in the kitchen of a restaurant. Dishwasher, deep fryer, 4 burner stove. The cooking equipment are under the hood so some of the heat will be taken out (if it can be called that) by the exhaust of air through...

Hi,
Are there any health reasons for mandating (by code) to have 75 cfm exhaust per fixture in public bathrooms? A client has asked that we don't design per 75 cfm code, and that he will get us a variance from the local code authority. The State board of PE's requires us to design with the...

Hi,
I have autocad 2006 running. I want to add a few bottons to the top menue line, such as "save as", "match propoerties" and "quick leader". In 2004 I could just drag the icon for these commands from a list to that top line, but now it all has changed. I have looked at the instructions but I...

RPZ requires horizontal installation. Most of the lease finish-outs don't have space allocated for this install. Is above the ceiling acceptable and ok location?

What would be the fixture count for these new high efficiency toilt fixtures. I have 1.3 gpf Water closets and 1 pint urinals in a public building. Need to size the swere lines but not sure if the old fixture counts would lead to larger than needed pipes.

Hi,
Is there any building code that requires a non-residential restroom to have floor drain. Typical restrooms in an office building for example.

Hi,
I am not sure if this is the right forum-please advise if not.
Is there any building code that states that a none-residential restroom must have a floor drain? My architect contacts say that they don't know of any.
thanks,
What is a max rule of thumb for distance between the condensor and evaporator for typical small (around 10 ton) units on commercial retail buildings? Can refrigerant lines be oversized to reduce pressure drop? Is there a vertical distance rise/fall limit? Should the unit be ordered with any...
When using the plotstyle, the text on the paper comes out much too thick that is not readable. All other lines are good. If I use the default acad plot style the text is good, and other lines are somwhat thinner but ok. How can I just reduce the line thickness of the text on plotting.

Hi,
I am having a hard time finding the published CFM from typical ceiling fans (commercial or residential). It seems that the manufacturers don't particularly emphasise the cfm on these products.
thanks,
I am designing a small SS lift station with a grinder pump. After the pump, the line needs to go horizontal for 100 ft. before rising up 10 ft. I need to prevent the line from draining back into the sump. Can a check valve be used at the pump discharge? What about the settlement issue on the...
