QNEET-2024-Ph-167: NEET 2024 Physics - Class 11 NEET-2024-Ph-167 Solution: An ideal fluid is flowing in a non-uniform cross-sectional tube …
An ideal fluid is flowing in a non-uniform cross-sectional tube XY (as shown in the figure) from end X to end Y. If and are the kinetic energy per unit volume of the fluid at X and Y respectively then the correct option is:
Multiple Choice Options
- A K 1 _ = K 2 _
- B 2 K 1 _ = K 2 _
- C K_1>K_2 K 1 _ > K 2 _
- D K_1 < K_2 K 1 _ < K 2 _
Step-by-Step Verified Solution
According to Bernoulli's principle,
Kinetic energy per unit volume + Potential energy per unit volume + Pressure = Constant
1 2 _ V 2 + _ g h + P = constant
Apply Bernoulli's principle at point X and Y ,
P + K 1 + _ g ( 0 ) = P + K 2 + _ g ( h ) K 1 = K 2 + _ g h K 1 > K 2
