Strategies for Bernoulli’s s Equation:• Read, draw, and label a rough sketch with givens.• The height h of of a fluid is is from a common referencepoint to to the center of of mass of of the fluid.• In In Bernoulli’s equation, the density is massdensity and the appropriate units are kg/m 3 ..• Write Bernoulli’s equation for the problem andsimplify by eliminating those factors that do notchange.P gh ½v P gh ½v2 21 1 1 2 2 2
Strategies (Continued)P gh ½v P gh ½v2 21 1 1 2 2 2• For a stationary fluid, v 1 = v 2 and we have:P P = g(h 22 -h 11 ))h = 1000kg/m 3• For a horizontal pipe, h 1 = h 2 and we obtain:P P ½v ½v2 21 2 2 1
