Name: Student I.D.:
1 A large movable plate is located between two large fixed pates as shown. Two
Newtonian fluids having the viscosities indicated are contained between the
plates. Determine the magnitude and direction of the shearing stress that act on
the fixed plates when the moving plate has a velocity of 4 m/s as shown. Assume
that the velocity distribution between plates is linear.
SHAPE \* MERGEFORMAT
The velocity field of a flow is given by:
V = [10y/(x2+y2)1/2] i [10x / (x2+y2)1/2] j m/s. Where x, and y are in meter. Determine the fluid velocity at points along the xaxis and along the yaxis. What is the angle between the velocity vector and the xaxis at a point (x,y) = (5,0), (5,5), and (0,5).
Water flows through a constant diameter pipe with a uniform velocity given by : V = [(8/t) +5] j m/s. Where t is in sec. Determine the acceleration at time t = 1, 2 , and 10 sec.
