Unformatted text preview: 2. (1.5 pts) All of the water from the large diameter pipe in the previous problem is fed into a smaller pipe of cross sectional area 0.1 m 2 . a) What is the flow rate in the smaller pipe? b) What is the flow velocity? 3. (1.5 pts) If the pipes in the previous problems lie horizontally, in which pipe is the pressure greater, the larger-area or smaller-area one? Explain your reasoning, using Bernoulli’s Principle, in one sentence. continuity: I = A 1 v 1 = A 2 v 2 Bernoulli equation: Δ P+ Δ ( ½ρ v 2 )+ Δ ( ρ gh) = Δ E pump /vol - IR...
