A vertical film of a viscous liquid (density 1000kg/m, viscosity 0.1kg/ms) is held between two vertical belts that are both moving upwards with a speed V. The separation between the belts is H=0.011m. The width of the belts is 1m. Calculate the value of V required to make sure that there is no net volume flow rate of fluid downwards. Give your answer as a positive number in m/s to two decimal places. The velocity profile between the belts is given by u= Pg H 4 4 (x) - v V - X where x is the horizontal distance from the centreline.
