Question

The total heat loss from a structurally tight glass greenhouse occurs through infiltration is

• A. \(10%\)
• B. \(20%\)
• C. \(30%\)
• D. \(40%\)

Hint:

In a tight greenhouse, infiltration heat loss is small because air leakage is reduced.

Answer 1

The Correct Option is A

Concept:
Heat loss from a greenhouse occurs through conduction, radiation, ventilation, and infiltration.

Step 1: Infiltration means unwanted entry of outside air into the greenhouse through small cracks, openings, or gaps.

Step 2: A structurally tight glass greenhouse has fewer leaks and openings.

Step 3: Therefore, heat loss through infiltration is comparatively low.

Step 4: For a structurally tight glass greenhouse, total heat loss through infiltration is about: \[ 10% \]

Step 5: Hence, the correct answer is \(10%\). \[ \boxed{10%} \]
