A system carries crude oil of specific gravity 0.8. The volumetric flow rate at point 1 (the inlet) is 10 ft3/s. Branch 1 is 5in. in diameter. Branch 2 is 4in. in diameter. Branch 3 is 3in. in diameter. All three branches are in a horizontal plane, and friction is negligible. Each branch has a pressure gauge. The pressure gauge at point 1 (the inlet) reads 25 psig and the pressure gauge at point 3 (an outlet) reads 20psig. What is the pressure at point 2 (another outlet)? Can the Bernoulli's equation be applied when 1 stream divides into 2?
