Water flows through a horizontal pipe that constricts from radius 5 cm to 2 cm: - In wide section (5 cm): Velocity = 1.0 m/s, Pressure = 150 kPa - In narrow constriction (2 cm): Velocity = 6.25 m/s, Pressure = 131 kPa By Bernoulli's principle, as fluid velocity increases through the constriction, fluid pressure:

Higher velocity = lower pressure (150 to 131 kPa).

Masterclass Solution & Distractor Trap Analysis

Continuity requires velocity to increase in narrow sections. Bernoulli's principle dictates that higher velocity corresponds to lower static pressure (150 kPa -> 131 kPa)....
