CHAPTER 4. NON-TECHINCIAL ASPECT 4.1. INTRODUCTION The chapter highlights the non-technical aspects of ventilation systems in sports halls, focusing on their economic, environmental, and social impacts. Economically, efficient ventilation systems can reduce energy costs and maintenance expenses, enhancing the facility's value and attracting more users. Environmentally, these systems help lower the carbon footprint by minimizing energy consumption and supporting sustainability goals. Socially, improved air quality and climate control enhance the health and comfort of athletes, spectators, and staff, promoting a positive community image and increasing participation in sports activities. Thus, effective ventilation systems are crucial for holistic sports facility management. 4.2. FINANCIAL & COST OF PROJECT The cost of a ventilation system for a sports area hinges on several key components. Firstly, ductwork expenses are influenced by factors such as material choice, size, and installation requirements. Similarly, diffusers, essential for distributing airflow, vary in cost based on design and quantity needed. Fans, along with volume dampers for airflow regulation, constitute another significant expense, dependent on factors like size and energy efficiency. Lastly, hangers, necessary for supporting ductwork, also contribute to overall costs. Balancing these factors ensures the ventilation system effectively meets the area's needs while remaining within budget constraints. The prices are shown in Table 4-1. 4.3. EHTICAL & SOCIAL The design of a ventilation system for a sports area involves ethical and social considerations that extend beyond technical aspects. Ethically, ensuring the health and safety of athletes, spectators, and staff is paramount. Adequate ventilation helps maintain indoor air quality, reducing the risk of respiratory issues and the spread of airborne illnesses, which is particularly crucial in light of recent public health concerns. Additionally, considering the environmental impact of the ventilation system, such as energy efficiency and carbon emissions, aligns with ethical principles of sustainability. 4.4. ENVIROMENT AND SUSTAINBILITY One aspect of environmental sustainability involves minimizing energy consumption. Designing ventilation systems with energy-efficient components, such as high-efficiency fans and motors, can reduce energy usage and greenhouse gas emissions. Additionally, incorporating advanced control systems, such as variable air volume (VAV) systems or demand-controlled ventilation, can further optimize energy efficiency by adjusting airflow based on occupancy and activity levels in the sports area. Furthermore, selecting environmentally friendly materials for ductwork, diffusers, and other system components can reduce the environmental footprint of the ventilation system. Using recycled materials or those with low embodied carbon can help minimize resource depletion and environmental pollution.

i need the answer quickly

I already calculated the viscosity to be 1.91  but I don't know how to derive the propagation error calculation of viscosity.  help

Which one of the following is a wrong statement. Paint is a non-Newtonian fluid Water and air are Newtonian fluid The viscosity of any real fluid is zere The viscosity of an ideal fluid is zero

What is the specific? weight of nitrogen in units of new temper cubeter. at the temperature of minus 10 Celsius and the pressure of 0.6 bar gauge ?  Please. I want you to give me details in how you confirm each unit.

How many types of Newton law do we have?

i dont really understand the explanation of part b or how they used trigonometry to get that. can you please help.

Question 2

Given that p = fluid density, V = fluid velocity, L = characteristic length, and p = dynamic ?viscosity. Which of the following quantities is dimensionless

Suppose you are given data in SI units (mass in kg and length i  meters)and because there is such a large number of calculating to be made you prefer to use the data as given rather converting them all. Modify the given equation so that the pressure drop calculated would be in bf/ft2 but the other terms would be in si units
