A storage room
common sense lol
Answer:
3150 L/min
Explanation:
The volume of the room is the product of the height of the room and its area. It is given as:
Volume (V) = height (h) × Area (A)
V = h × A
Height = 2.7 m, Area = 200 m². Hence:
V = h × A = 2.7 × 200 = 540 m³
The flow capacity (
) is given by

ACH = air changes per hour = 0.35

But 1 m³ = 1000 L, 1 hr = 60 min
Answer:
Explanation:
The pictures below shows the whole explanation for the problem
Answer:
i) 0.610 m or 610 mm
ii) 0.4 m or 400 mm
Explanation:
The pressure difference between the pipes is
a) Air
Pa + πha +Ha = Pb + πhb +Hb
Pa - Pb = π(hb-ha) + Hb-Ha
Relative density of air = 1.2754 kg /m3
Pa - Pb = 1.2754 * 0.4 + (0.3-0.2) = 0.610 m or 610 mm
b) paraffin of relative density of 0.75
Pa - Pb = π(hb-ha) + Hb-Ha
Pa - Pb = 0.75 * 0.4 + (0.3-0.2) = 0.4 m or 400 mm
