An oil is contained between 2 identical parallel plates of 2m2area each. The top plate is pulled tothe left (-x direction) with a force of 0.33N at a velocity of 0.3 m/s. The bottom plate is pulled in theopposite direction with a force of 0.11N at a velocity of 0.1 m/s. The plates are 5mm apart. Whatis the viscosity of the oil in cP?
(b) Consider two identical water tanks (20 m x 10 m x 10 m) filled with water. The depth
of water in the first tank is 8 m and it is stationary. The depth of water in the second tank is 6
m and it is moving vertically downward with a constant acceleration of 3.3 m/s?. Which tank
will have a higher pressure at the bottom?
Now, the first tank is moving horizontally in the direction of its length with a constant
acceleration of 2.4 m/s?. Determine the shape of the free surface and the total force on the
base and vertical faces of this tank.
What will happen if these tanks are completely filled with water?
Consider a body of arbitrary shape. If the pressure distribution over thesurface of the body is constant, prove that the resultant pressure force onthe body is zero.

- The basic barometer can be used as an altitude measuring device in airplanes. The ground control reports a barometric reading of 753mmHg while the pilot's reading is 690mmHg. Estimate the altitude of the plane from ground level if the average air density is 1.20 kg.m-3 and the barometer fluid is mercury, PHg=13600 kg.m3. To solve this problem determine the atmospheric pressure on the ground and then in the air using the barometric pressure readings. Then using the pressure difference between the ground and the plane, the altitude can be derived by considering a column of air from the ground up to the plane, of constant density, in a similar manner to the barometer.
