SELECTION OF COEFFICIENT OF UTILIZATION

1. Determine cavity ratios by formula:

5 x hcc x (L + W)

(L x W)

5 x 1.64 x (39 + 22)

(39 x 22)

5 x hrc x (L + W)

(L x W)

5 x 4.92 x (39 + 22)

(39 x 22)

2. Obtain ef fective cei ling cavi ty ref lectances (pcc) from Table A; pcc = 71%

3. Obtain effective floor cavity reflectances (pfc) from Table A; pfc = 19%

4. Find coefficient of util ization from published data (for pfc=20%) C.U. = 0.66

using RCR, pcc and wall reflectance.
