In a room 18x22 ft, the total light incident on the horizontal workplace is 10,000 Lm. Calculate the illuminance on the workplace is
Added by Veronica W.
Step 1
The area (A) can be calculated using the formula: \[ A = \text{length} \times \text{width} \] Given the dimensions of the room are 18 ft by 22 ft: \[ A = 18 \, \text{ft} \times 22 \, \text{ft} = 396 \, \text{ft}^2 \] Show more…

An office 17m by 8m wide is lighted by 8 lamps, and each lamp has a luminous intensity of 200cd. Allowing for an absorption loss of 4000lm for the reflectors, walls, and ceiling, calculate the average illumination on the working plane. Ans 118.4 lm/m^2

A floodlight emitting 25,000 candelas in the center of its beam is aimed at 60 degrees to a point on the ground 20 m away. What is the illuminance of the point in lux? A room measuring 40 ft by 80 ft is to be illuminated by fluorescent lamps having an output of 3,300 lumens per lamp arranged in 4 rows. The required illuminance at the floor is 60 fc. What is the number of lamps required in each row if the luminaire efficiency is 42%?
