The dobhoff tube goes from nose to small intestine duodenum. The nasogastric (NG) tube goes from nose to stomach.
More in-depth answer: A dobhoff tube is a small-bore feeding tube that runs from one of the nares to the stomach, then to the first part of the small intestine (duodenum). It can be advanced blindly 10 more cm to see if it can be threaded through the pyloric valve, but if it keeps coiling in the stomach, most doctors will order to place it the rest of the way under fluoroscopy. It can also be bridled in for extra security. This is mainly a feeding tube and can stay in for weeks to a few months.
An NG tube is a large-bore tube that is used for many different reasons, including decompressing the stomach for surgery and to prevent nausea/vomiting. It is NOT used for tube feedings. Usually this tube does not stay in for very long.

A boiling tube is for boiling chemicals or metals, a test-tube is for holding chemical reactants. Test tubes are slimmer, boiling tubes are wide and are made of thin glass
Though they come in various sizes, test tubes are simply glass tubes. A graduated cylinder, however, has approximate measurements for varying volumes of liquid.

No. A ringstand is a stand with a base with a large pole sticking out of it. that you can attach rings to. A wire mesh is usually placed on the ring for setting a beaker to be heated. A test tube clamp can be attached to the ring stand to hold a test tube, for say, heating it in a hot water bath.

The main difference between tube and pipe arises while considering the standard dimensions. The nominal sizes for pipes and tubes are determined differently. For pipes, the ID or Internal Dimension is the pipe size and for tubes the OD or Outer Dimension is considered the tube size.

The answer is in the name. Boilers are made with a "tube - in - shell" construction, and the name implies what is in the tube. In a water tube boiler, the water circulates through the tubes, and the burner is usually under them. Most of the time, the "shell" of this style of boiler would not be watertight. A fire tube boiler has a watertight outer jacket with tubes through the center of it. The flame is shot through the tubes.
Pipe n tube are same in shape etc. BUT only difference is Pipe is used for Transferring Material (Gas, Liquid etc.) AND where it is used for Heat Exchanging purpose , It is called TUBE.

DobbHoff feeding tube was invented in 1976 by 2 surgeons Dr. Robert Dobbie and Dr. Hoffmeister - and so named after them.

"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
