To calculate the formula for duct sizing divide the room load by the whole house load. Next multiply those results by the equipment CFM.

Sizes are seldom stated in terms of weight. They are usually stated in terms of body measurements: chest, weight, hips, etc. Stocking sizes are sometimes stated in terms of weight and height, however there is no standard sizing system and you would have to look at the size chart for each brand. Also, sizing may be different for men's and women's garments and also different for petite, tall, big and husky, etc. And not all manufacturers adhere to standard sizing. Formal wear especially seems not to follow standards.
You chose your wakeboard by your weight, not your height. Here's a sizing chart to use: http://www.sportsoutletusa.com/wakeboard_specs.php
In order to calculate the area of HVAC duct offset and elbow, one must first measure the distance between the two. Then the elbow must be larger than any cross section to maintain airflow.
(Width 1 + Height 1 + Width 2 + Height 2)* Length

Yes cooling requires larger duct work. Typically you would size the duct work for the cooling system and heat will work fine as well
The chemical formula for duct tape is not a compound that can be represented by a single formula. Duct tape is a combination of different materials such as a cloth or plastic backing, an adhesive layer, and possibly a waterproof coating.
To calculate the duct diameter, you need to consider the airflow requirements, velocity of air in the duct, and the friction losses. Use the Duct Sizing Chart or an online calculator to determine the appropriate duct diameter for your system based on these factors. It's important to ensure that the chosen diameter can handle the required airflow without causing excessive pressure drop.
The best installation practices for 4-inch flex duct in a residential HVAC system include ensuring proper sizing, minimizing bends and kinks, sealing all connections tightly, supporting the duct properly, and avoiding sharp turns. Proper insulation and avoiding compression of the duct are also important for efficient and effective operation.
When determining the appropriate return duct sizing for a residential HVAC system, factors to consider include the size of the HVAC unit, the layout and size of the home, the number and location of supply vents, and the desired airflow rate. It is important to ensure that the return ducts are properly sized to allow for efficient air circulation and maintain a comfortable indoor temperature.
If the formula is something like AVERAGE, SUM, etc., then it will copy it to another cell. However, when using the sizing handle after just entering the formula alone, Excel will automatically fill in the answer. The formula is copied along with it, though. However, if the formula is in reference to the content of another cell, this will not happen. The formula changes if the formula uses the content of another cell. To keep it exactly the same to copy it down, you have to make the cell number in the formula an absolute value so it will not change.
When installing a hood duct in a kitchen, important considerations include proper sizing to match the hood, ensuring proper ventilation to the outside, following building codes and regulations, and considering the layout and design of the kitchen to optimize efficiency and aesthetics.

The cross-sectional area of a 10-inch round metal duct can be calculated using the formula for the area of a circle: A = Ļr^2, where r is the radius of the duct. For a 10-inch round duct, the radius would be half of the diameter (10 inches), so the radius is 5 inches. Plugging in this value into the formula gives A = Ļ*5^2 = 25Ļ square inches, or approximately 78.5 square inches.
