Assertion A: Loss of head at a sudden expansion of a pipe is larger than that at a sudden contraction.
Reason R: Separation of flow occurs at sudden contractions
The correct answer to this question is option 'C', which states that both Assertion A and Reason R are true, but R is not a correct explanation of A.
Explanation:
Loss of head at a sudden expansion of a pipe:
When the flow of fluid passes through a sudden expansion in a pipe, the velocity of the fluid decreases, resulting in an increase in pressure. This increase in pressure is due to the conversion of kinetic energy into potential energy. The loss of head at a sudden expansion is a result of this pressure increase.
Loss of head at a sudden contraction of a pipe:
When the flow of fluid passes through a sudden contraction in a pipe, the velocity of the fluid increases, resulting in a decrease in pressure. This decrease in pressure is due to the conversion of potential energy into kinetic energy. The loss of head at a sudden contraction is a result of this pressure decrease.
Separation of flow at sudden contractions:
The reason given for Assertion A is that separation of flow occurs at sudden contractions. This means that when the fluid passes through a sudden contraction, there is a tendency for the flow to separate from the pipe walls, leading to disturbances and turbulence in the flow. This separation of flow results in additional energy losses, contributing to the overall loss of head.
Correct explanation:
While it is true that separation of flow occurs at sudden contractions, it is not the only factor contributing to the loss of head at a sudden contraction. The increase in velocity and decrease in pressure also play significant roles in the overall loss of head. Therefore, Reason R is not a correct explanation of Assertion A.
In conclusion, both Assertion A and Reason R are true. However, Reason R is not a correct explanation of Assertion A.

Loss Due To Sudden Expansion: It is a type of minor loss at the end of a pipe or when smaller diameter pips meet large diameter pipe due to sudden enlargement in the area of flow. It is larger than loss due to sudden contraction because Eddies are formed at the entrance of a large diameter pipe.
Loss Due To Sudden Contraction: It is a type of minor loss when a large diameter pipe meets a small diameter pipe or a small diameter pipe attached to a water reservoir due to a sudden decrease in the area of flow. Separation of flow occurs at the entrance of a small diameter pipe.
