Hello,I am MHF and I am in a sustainability class and I (and some others) am getting no where with this" Practice Problem". I have been trying without getting it. Could someone just simplify this to me? Is it that hard to find the order of operations?...We have already been given back our possible 12 points papers and I got 3 pts.
The motor horse power of fans for an office building with 10,000 ft2,929m2 is 30 kw. The average diversity load within the building is 80%. The peek load is 176 kw and the design air flow is based on 60 f supply temperature and 75 f zone temp. Fans were selected at 27,545 cfm (13,000 L/s) at 4 in (0.996 kPa) total static pressure with a fan efficiency of 80%. If watts(W0 is L/s * K, calculate the zone temp. and the sensible load....? Any One? Thank You MHF.

@ MHF: Please ask your instructor for help with your particular "Practice Problem". If your instructor is having difficulty using this tool, they may post their question here.

Hi,
This is a fantastic tool to have!
Is it possible to modify the spreadsheet to use SI units?

Thanks and Regards,
