Practice Questions

Question 1

In the context of animal housing, which psychrometric property is most critical for assessing the potential for heat stress in livestock during periods of high humidity and temperature?

Question 2

A greenhouse manager is designing a ventilation system for a new facility. Given a target air exchange rate of $1.5$ air changes per minute (ACM) and a greenhouse volume of $2000 \text{ m}^3$, what is the required volumetric airflow rate in cubic meters per hour?

Question 3

Which advanced heating strategy in greenhouses utilizes a network of pipes embedded in the floor or benches to provide heat directly to the root zone, optimizing plant growth and energy efficiency?

Question 4

When designing a humidity control system for a high-density poultry house, which factor presents the most significant challenge in maintaining optimal relative humidity levels?

Question 5

A controlled environment agriculture (CEA) system aims to maximize crop yield and quality. If the vapor pressure deficit (VPD) is consistently too low, what is the most likely negative impact on plant physiological processes?
