5. A viscous liquid is to be coated onto a moving film as sketched in Fig. P6.5. The desired coating thickness is H=0.01 cm. For (b) and (c), use the following data:

1)Specify values of H1 and H0 that give this value of H ,while minimizing the pressure force developed under the blade. 2)Find the final liquid film thickness H in millimeters. 3)Find the vertical force required to hold the blade in place, in newtons.
