Question

PROBLEMS 1. A sliding plate viscometer with a 1.0 mm gap is shown. The top plate is moving to the right at a constant 1 m/s in response to a force of A.N. the bottom plate is What is the viscosity of the fluid? (Assume a linear velocity distribution.) 2. For the curved surface indicated in the diagram, determine the magnitude and location for: a) the Resultant Horizontal Force b) the Resultant Vertical Forces and c) the Resultant Total Force L1 = m, L2 = 3.00 m & gammafluid = 12753 N/m^3. This arrangement extends 1.50 m into the plane of the page. A river barge has the dimensions shown. What is the minimum width, W, required meters, for the barge to be stable in this configuration? CG is 20.0 ft above the of the barge. (GammaH2O = 62.4 lbf/ft^3)

Explanation / Answer

1) F = mu*A* (u/y)

4 = mu* (0.1 * 0.05) * ( 4/0.001)

mu = 0.2 Pa - s
