By systematically analyzing each parameter, they were able to refine the system design and optimize its operation to meet the specific requirements of the sports hall, ensuring optimal air quality and comfort for occupants. 3.6. CONCLUSION In summary, the components of a ventilation system, including fans, ductwork, dampers, and control systems, work together to ensure effective air circulation, temperature regulation, and air quality management within indoor spaces. Also, delved into the intricacies of ventilation system design, employing parametric studies and fundamental equations to elucidate key relationships governing system performance. Through comprehensive analyses, the chapter underscored the importance of various parameters on ventilation efficacy. The parametric studies revealed proportional expansions in exhaust flow, duct area, and pressure drop, highlighting the direct correlations between factors such as occupancy, room size, duct dimensions, and system resistance Prresure Drop (Pa) Variation of pressure drop (Pa) as Length of Duct Varies in (m) 350 275 300 242 250 250 200 150 100 50 300 308 0 50 55 70 85 90 Lenght of Duct (m) pressure drop (Pa) Figure 3-21 Variation of pressure drop (Pa) as Length of Duct Varies in (m) This finding underscores the direct correlation between duct length and pressure loss in ventilation systems. With a longer duct length, there is an increased resistance to airflow due to friction and turbulence within the duct, resulting in a higher pressure drop. Thus, the proportional expansion in pressure drop aligns with the increased duct length, highlighting the importance of considering duct design and layout to minimize pressure losses and optimize ventilation system performance. To compare equivalent duct sizes calculated by duct sizer tools and fluid dynamics equations, Calculate the equivalent duct diameters using standard duct sizing tools and independently with fluid dynamics equations. Finally, compare the results, noting any small discrepancies in mass flow rates to ensure design accuracy (Figure 3-22).

Hello I’m trying to make the graph that you see in the picture but I am having trouble on make the two lines that you see on the graph to over lap each other, I don’t want the two lines to be separate I want the two lines on top of eachother like you see in the picture please fix the code so that the Diesel line is on top of the Petrol line as seen on the picture. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Fix the random seed for reproducibility rng(45); % Assumed positions of cars CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves pDiesel = polyfit(carPosition, CO2Diesel, 3); pPetrol = polyfit(carPosition, CO2Petrol, 3); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition); fitPetrol = polyval(pPetrol, carPosition); % Plotting the data figure; hold on;…

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5.  1 pass 2 fail 3 fail 4 pass

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
