Question

the U-tube of a manometer has:
(A) One side open
(B) Both side open
(C) Both sides closed
(D) None of these

Answer 1

Hint : To solve this question we have to know about U-tube manometer. We know that, As the name refers to, a U-tube manometer is made up of two parallel tubes joined together in the form of the letter “U.” The two parallel tubes basically constitute the limbs of the device. Whether it’s for the measurement of pressure in a fluid, liquid, or gas, U-tube manometers may be employed for most purposes.

Complete Step By Step Answer:
We know that, U-tube Differential Manometer It is a device that is used to measure the pressure difference between two points in a pipe or between two different pipes. This manometer consists of a U shaped tube containing a heavy liquid. The two ends are connected to the two desired points in the pipe whose difference of pressure is required.
A U-Tube manometer has two arms and is filled with a manometer liquid. One arm is connected to the vessel in which fluid (whose pressure is to be measured) is filled and another ram is open so that the liquid can rise or fall.
So, the right answer will be option number A. one side open.

Note :
We have to know that the two parallel tubes basically constitute the limbs of the device. Whether it’s for the measurement of pressure in a fluid, liquid, or gas, U-tube manometers may be employed for most purposes. They may be used in different positions such as inverted, upright, or inclined.
