Question
Water flows through a frictionless duct with a cross-section varying as shown in fig. Pressure p at points along the axis is represented by
The correct answer is:
When cross-section of duct is decreased, the velocity of water increased and in accordance with Bernoulli’s theorem, the pressure P decreased at that place
