Discharge
Explanation:
Since it is the same discharge (within the small diameter pipe and within the large dimater pipe), velocities are different. A stands for cross sectional area of pipes and v stands for velocities. Just equalize:
when you arrange the above equation:
Velocity in the second (less dimater pipe) is 180
