Question

Water flows in the horizontal pipe shown in the figure.

At point A the area is 26.0 cm² and the speed of the water is 2.20 m/s. At B the area is 15.0 cm². The fluid in the manometer is mercury, which has a density of 13,600 kg/m³. We can treat water as an ideal fluid having a density of 1000 kg/m³. What is the manometer reading h?

Question 10 (1 point) Water flows in the horizontal pipe shown in the figure. - A B - At point A the area is 26.0 cm- and the speed of the water is 2.20 m/s. At B the area is 15.0 cm2. The fluid in the manometer is mercury, which has a density of 13,600 kg/m². We can treat water as an ideal fluid having a density of 1000 kg/m². What is the manometer reading h?
