Chapter 6 Viscous Flow in Ducts - Simon Fraser University

Chapter 6 • Viscous Flow in Ducts P6.1 An engineer claims that flow of SAE 30W oil, at 20 C, through a 5-cm-diameter smooth pipe at 1 million N/h, is laminar. Do you agree? A million newtons is a lot, so this sounds like an awfully high flow rate. Solution: For SAE 30W oil at 20 C (Table A.3), take ρ = 891 kg/m3 and μ = 0.29 kg/m-s.

Bernoulli’s Equation | Physics - Lumen Learning

Let us first consider the very simple situation where the fluid is static—that is, v 1 = v 2 = 0.Bernoulli’s equation in that case is P 1 + ρgh 1 = P 2 + ρgh 2. We can further simplify the equation by taking h 2 = 0 (we can always choose some height to be zero, just as we often have done for other situations involving the gravitational force, and take all other heights to be relative to
