There was no duct tape in the 1940's
1874
Originally it WAS called duck tape, because of its waterproof 'abilities' but the name was forgotten and changed to duct tape because it was originally silver like the ducts that it repaired.
In 1963, duct tape was priced around 50 cents to a dollar per roll, depending on the brand and retailer. This price reflects the economic conditions of the time and the tape's growing popularity for various household and industrial uses. Adjusted for inflation, that would be roughly equivalent to about $4 to $8 today.
Duct tape was originally called Duck tape. It was green in color and used in the Military first. Generally used to tape Ammo cans shut. After WWII the tape was colored silver and used on Air Ducts during the housing boom when the troops came home. Duct tape can be used in emergency situations to repair almost anything, it can help house windows withstand hurricane winds, hold car bumper covers on and restrain prisoner's hands and feet in the event hand cuffs are unavailable.

cystic duct and the hepatic duct
Oh, dude, calculating duct area is like figuring out how much space your air is gonna flow through. Just multiply the width by the height of the duct to get the area. It's not rocket science, but hey, it's important for making sure your air conditioning doesn't end up like a sad deflated balloon.
The merger of the cystic duct and the common hepatic duct forms the common bile duct. This duct carries bile from the liver and gallbladder to the small intestine for digestion.
common bile duct
The common bile duct is formed by the joining of the common hepatic duct (from the liver) and the cystic duct (from the gallbladder).
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.
The duct that transports bile from the gallbladder to the common bile duct is called the cystic duct. It is a small tube that connects the gallbladder to the common bile duct, allowing bile produced by the liver and stored in the gallbladder to flow into the small intestine for digestion.
