Problem Strategy for Rate of Flow:• Read, draw, and label given information.• The rate of flow R is is volume per unit time.• When cross-section section changes, R is is constant.R v A v A1 1 2 2• Be sure to use consistent units for areaand velocity.
Problem Strategy (Continued):• Since the area A of of a pipe is is proportional to to itsitsdiameter d, , a more useful equation is:is:2 vd21 1 2 2vd• The units of of area, velocity, or or diameter chosenfor one section of of pipe must be consistent withthose used for any other section of of pipe.
