Assertion: The velocity increases, when water flowing in broader pipe enter a narrow pipe.
Reason: According to equation of continuity, product of area and velocity is constant.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

if assertion is true but reason is false.

D

if both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
In a streamlines flow of a liquid, according to equation of continuity `av`=constant.
Where `a` is the area of cross section and `v` is the velocity of liquid flow. When water flowing in a broader pipe enters a narrow pipe, the area of cross section of water decreases therefore the velocity of water increases.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 : The velocity increase, when water flowing in broader pipe enter a narrow pipe. STATEMENT-2 : According to equation of continuity, product of area and velocity is constant.

Why dies velocity increase when water flowing in broader pipe enters a narrow pipe?

Assertion: A fluid flowing out of a small hole in a vessel apply a backward thrust on the vessel. Reason: According to equation of continuity, the product of area and velocity remain constant.

Assertion: The velocity of flow of a liquid is smaller when pressure is larger and viceversa. Reason: According to Bernoulli's theorem, for the stream line flow of an ideal liquid, the totla energy per unit mass remains constant.

The velocity of the water flowing from the inlet pipe is less than the velocity of water flowing out from the spin pipe B. Then

Assertion : Fundamental frequency of a narrow pipe is more. Reason : According to laplace end correction if radius of pipe is lass, frequency should be more.

Assertion : The man who fits or fixes water pipes in our homes etc. is called a plumber Reason: Pipes used for carrying water were made up of lead at one time.

Assertion: Reynolds number determines the nature of flow of a liquid through a pipe. Reason: For streamlined flow, the critical velocity should be as small as possible.
