A classroom of 12m × 25m × 4m requires 3 air changes per hour. At an air velocity of 2 m/s, the necessary duct cross section (in m²) is

1. 0.50
1. 0.75
1. 1.00
1. 1.25

3 air changes per hour means 3 times the volume of room changes in one hour.
So,
Volume rate per second = 3 × Volume of room m³/sec
3600

Volume rate per second = 3 × 12 × 25 × 4 m³/sec
3600

Volume rate per second = 1 m³/sec
Area = Volume rate per second/ velocity
Area = 1/2
Area = 0.5 m²

Correct Option: A

The respective lengths of shadows generated for a free standing wall of given height L by sunlight incident at angles of 30°, 45°, 60°, 90° to the horizontal are

1. L L 3, L, ,0 3
1. L L, L 3, ,0 3

The respective lengths of shadows generated for a free standing wall of given height L by sunlight incident at angles of 30, 45, 60 and 90 degrees to the horizontal are:
Length of shadow, l = height /tan α, where α = angle with horizontal.
For 30°, l = L L = L √3 . Similarly
(1/√3)

for 45°, l = L
for 60°, l = L/√3
for 90°, l = 0
