There are going to be allot of varying opinions on this one but it's fairly simple to get in a good ball park. You want between 600 to 800 feet per minute of air flow so you need to know the CFM of your air handler and then you can calculate it this way. Ftcube /min divide by Ft / Min = Ft square. At 1200 CFM for a flow rate of 800 Ft/min you get a result of 1.5 square feet which is 216 square inches. If you divide by 8 for the prefab 8 inch duct you need a 27 inch wide dimension or 16 X 13.5. Good luck on your project.

The time it takes to burn off 4,000 calories depends on several factors, including your weight, activity level, and the type of exercise you're doing. On average, a person may burn around 300-600 calories per hour with moderate to vigorous exercise. However, this can vary significantly. Here's a rough estimate of the time it might take to burn 4,000 calories for a person with an average calorie burn rate: Walking: If you're walking at a moderate pace (3-4 mph), you might burn around 250-400 calories per hour. So, it could take approximately 10-16 hours of walking to burn off 4,000 calories. Running: Running at a moderate pace (5-6 mph) can burn around 600-800 calories per hour. It would take about 5-7 hours of running to burn 4,000 calories. Biking: Cycling at a moderate speed (12-14 mph) can also burn around 600-800 calories per hour. It would take approximately 5-7 hours of cycling to burn off 4,000 calories. Swimming: Swimming can be an effective way to burn calories, and you might burn 500-700 calories per hour. So, it would take roughly 6-8 hours of swimming to burn 4,000 calories. High-Intensity Interval Training (HIIT): HIIT workouts can be very effective for calorie burning. Depending on the intensity, you might burn 400-800 calories in an hour. So, it could take 5-10 hours of HIIT to burn 4,000 calories. Please note that these are approximate estimates, and individual calorie burn rates can vary significantly. Your age, gender, fitness level, and other factors can influence how many calories you burn during exercise. It's also important to consider that diet and overall lifestyle play a significant role in managing your calorie balance. If you're trying to lose weight or manage your calorie intake, it's often more practical to focus on your diet in addition to exercise.
