Unformatted text preview: per unit mass is constant = u2/2 + P/ + gz • u12/2 + P1/ + gz1 = u22/2 + P2/ + gz2 + losses Bernoulli Equation • If using the average crosssectional flow for u in the Bernoulli equation, the average kinetic energy (~u2) will be poorly estimated. • include a kinetic energy correction factor, dA u u(r) A 1 α A 3 ∫ = ( α = 2 for laminar/circular, 1.011.1 for turbulent flow)...
