The fluid flowing between two parallel plates has an absolute viscosity (μ) = 0.82 ns/m2 and density (rho) = 1280 kg/m3.calculate the intensity of shear stress (τ) in pa, at y = 3 cm, assuming a straight-line velocity distribution. given velocity of top plate, u = 120 cm/s and width b = 8 cm.

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
