RE-NEET 2026 Physics Flow of Fluids MCQ Question
Type: MCQ-numerical-Medium-Class 11
Water flows in a streamline motion through a horizontal pipe of circular cross-section as shown in the figure. The pressure difference of water between P and Q is 15 Nm⁻². The area of cross-section at P and Q are 40 cm² and 20 cm², respectively. The rate of flow of water through the pipe, in cm³s⁻¹, is : [Take density of water=1000 kg m⁻³]
A
200
B
300
C
400
D
100
Correct Answer
Option C
Detailed Explanation
Using the equation of continuity and Bernoulli's principle, the rate of flow can be calculated. The pressure difference and area change are used to find the velocity and hence the flow rate.
