Task id10625
Determine the friction force and tangential stress on an area a x b = 10 x 10 cm2 at a water temperature t = 14°C and a velocity difference between two adjacent layers of thickness dn = 0.25 mm, equal to du = 0.0003 m/min. Dynamic viscosity at a given temperature ?14 = 17.92•10-4 N•s/m2.
