A two-dimensional fluid element of dimensions dx and dy translates and distorts as shown in Fig. P469
Question:
A two-dimensional fluid element of dimensions dx and dy translates and distorts as shown in Fig. P4–69 during the infinitesimal time period dt = t2 – t1. The velocity components at point P at the initial time are u and ν in the x- and y-directions, respectively. Consider the line segment PA in Fig. P4–69, and show that the magnitude of the linear strain rate in the x-direction is
