Aula Prática 5 Balanços de massa e problemas com tensões de corte

2
Balanço de massa This evolution equation states that the rate of change inside a control volume balances the fluxes, plus sources minus sinks. Derive the equation for mass balance. Simplify it for a 1D system where velocity is uniform at the inlet and the outlet.

Tensões de corte y h Draw the shear stress profile and compute the maximum and minimum. The figure shows the velocity profile in a flow between two parallel plates. The velocity profile is a parabola and as a consequence the shear stress is a straight line, since it is proportional to the velocity gradient: The shear stress is zero at y=0 and is maximum at maximum y, i.e. at h/2 https://ecourses.ou.edu/cgi- bin/ebook.cgi?doc=&topic=fl&chap_sec=08.1&page=theory
