For incompressible flow this can be easily integrated between points (1) and (2) to give (along a streamline) 3) Rotational Effects Care must be used in applying the Bernoulli equation across streamlines. If the flow is (i.e., the fluid particles do not as they move), it is “irrotational” “spin” appropriate to use the Bernoulli equation across streamlines. However, if the flow is (fluid particles use of the Bernoulli equation is “rotational” “spin”), restricted to flow along a streamline.
