A typical 60-watt standard frosted incandescent bulb outputs 890 lumens for an efficacy ratio of about 15 lumens per watt. As an A19, its shape is spherical. What is the its calculated luminance? A. 25,115 cd/in² B. 25.115 cd/ft² C. 25,115 cd/m² D. Indeterminate, missing variable. Answer If 1 candela (cd) = 4 ∏ lumens (lm), 890 x 1cd/4∏ = 71 cd, A19 = 19/8 = 2.375 in or 60mm diameter (= 30mm radius), L = intensity / projected area, 71 cd / ∏ r² = 71/ 3.14 x (.03m)² = 25,115 cd/m² ARE 4.0 exam prep: BS
10 days for the Architect to ACT, but 30 days from the date of filing the claim before the Owner or Contractor can request Arbitration.
ReplyDeleteMediation would be sought before proceeding to binding dispute resolution (arbitration or litigation - whichever checkbox is selected in A101).
