What bra cup size is equal to an h?
An H cup size typically falls under the U.S. sizing system and is generally considered to be equivalent to a UK size HH. However, it's important to note that sizing can vary between brands and styles, so it's advisable to check specific sizing charts for accurate measurements.
What does 11c mean in shoes?
In shoe sizing, "11C" typically refers to a size 11 shoe with a "C" width designation. The "C" width indicates a standard width for women's shoes, while in men's sizing, it may denote a narrower width. Different brands may have slight variations in their sizing systems, so it's essential to check each brand's specific size chart for accuracy.
What is the equivalent to a womens size 9 shoe?
A women's size 9 shoe is generally equivalent to a men's size 7.5, as there is typically a 1.5 to 2 size difference between men's and women's shoe sizes. In European sizing, a women's size 9 usually corresponds to a size 40.5 or 41. However, sizing can vary by brand, so it's always best to check specific sizing charts when purchasing shoes.
Is a 38ddd or 38f bigger bra size?
A 38F bra size is larger than a 38DDD. The "DDD" size typically corresponds to the same volume as "F" in many sizing systems, but it can vary by brand. Generally, in numerical sizing, the "F" is considered a step up in cup size from "DDD."

Is duct sizing for cooling diff from heating?
Yes cooling requires larger duct work. Typically you would size the duct work for the cooling system and heat will work fine as well
What is the chemical formula for duct tape?
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.
How do you work out duct diametre?
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.
How do you take hvac elbow duct size?
To determine the appropriate size for an HVAC elbow duct, first measure the diameter of the duct it will connect to. Use the duct calculator or duct sizing charts to find the equivalent diameter based on airflow needs, considering the type of material and installation specifics. It’s important to account for the angle of the elbow, as this can affect airflow resistance. Finally, ensure that the chosen size maintains efficient airflow while minimizing noise and energy loss.
What are the best installation practices for 4 flex duct in a residential HVAC system?
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.
What factors should be considered when determining the appropriate return duct sizing for a residential HVAC system?
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.
Does the sizing handle allow you to copy a formula from 1 cell to another cell?
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.
What are the important considerations to keep in mind when installing a hood duct in a kitchen?
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.
How do you find cfm in duct?
To find cubic feet per minute (CFM) in a duct, you can use the formula: CFM = Air Velocity (feet per minute) × Duct Area (square feet). Measure the air velocity using an anemometer and calculate the duct area by multiplying the width and height for rectangular ducts or using the formula for the area of a circle (π × radius²) for round ducts. Multiply these two values to get the CFM. Alternatively, you can use duct flow measurement devices or tools for an accurate reading.
What is pattern sizing?

What is the cross-sectional area of a 10-in round metal duct?
The cross-sectional area of a 10-inch round metal duct can be calculated using the formula for the area of a circle: A = πr^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 = π*5^2 = 25π square inches, or approximately 78.5 square inches.
