A rectangular duct is a type of air distribution component used in HVAC (heating, ventilation, and air conditioning) systems to transport air. It is characterized by its rectangular shape, which allows for efficient airflow and space utilization in buildings. Rectangular ducts are typically made from materials like galvanized steel, aluminum, or flexible plastic, and they come in various sizes to accommodate different air volume requirements. Their design helps reduce air resistance and improve system efficiency compared to round ducts in certain applications.

width always comes first
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.
cystic duct and the hepatic duct
I really dont know but I will tell you to check out some articles at www.High Beam.com and you can check out HGTV on TV and they always put in insulation!
common bile ductThe common bile duct.
common bile duct
Assuming the duct you have in mind is in a 3d shape (length, width, and depth) Your answer will be in a cubic form. Example: Say it is 2 feet long 1 foot wide and 1 foot tall, the area will be 2 cubic feet. Measurement of side one * side 2 * side 3 = area.
The Cystic duct from the gallbladder and the Common Hepatic duct from the liver
Stenson's duct
In pigs, the duct from the gallbladder is called the cystic duct, which merges with the common hepatic duct to form the common bile duct. This common bile duct then carries bile from the liver and gallbladder to the duodenum for digestion.
Hepatic duct is attached with liver. The union of hepatic duct and cystic duct forms common bile duct.
