N/m? 1.W1: two horizontal plates are placed 1.25cm apart, the space between them being filled with oil of viscosity 14 poises. Calculate the shear stress in oil if upper plate is moved with a velocity of 2.5 m/s. H.W2: two large plate surfaces are 2.4cm. the space between the surface if filled with glycerin . what force is required to drag a very thin plate of surface area 0.5m² between the two large plane surfaces speed of 0.6m/s, if: a) The thin plate is in the middle of the two plate surfaces. b) The thin plate is at a distance of 0.8cm from one of the plane surfaces. Take the dynamic viscosity of glycerin = 8.1*10-1 N s/m². H.W3: if the viscosity of water at 68°F is 0.01008 poise, compute its viscosity in (Ib.s/ft).if the (S.G = 0.998) at 68°F compute its kinematic viscosity in ft- /s? H.W4:10in diameter plunger slides in a 10.006in diameter cylinder, the annular space being filled with oil having a viscosity 0.004 ft2/s and (S.G =0.85).if the plunger moves at 0.6ft/s.find the resistance when 9ft is engaged in the cylinder.
