Question 3 (25/100). Water flows at a constant rate of 1.2 m³/s from a wide channel with a cross-sectional area of 6 m² to a narrower channel with a cross-sectional area of 2 m². The flow is steady, the liquids are at equal heights (z?=z?), and friction losses are neglected. What is the pressure difference between the two points in Pa? (?water = 1000 kg/m³).
