A horizontal water pipe goes from a large diameter to a small diameter and then back to the first diameter as shown in the figure below. The level of water (8cm in the larger tube and 4 cm in the constricted tube) in the small vertical tubes provides us with information about the water pressure in the two different sizes of pipe. The inside diameter of the larger pipe is 2.60 cm and water travels through both sizes of pipe with a volume flow rate of 2.00 10-4 m3/s. Determine the inside diameter of the smaller pipe.
I have attempted many times by combining Bernoulli's Equation with the equation of continuity to no avail. Please help.
