a. An 8cm water jet with a velocity of 25m/s impinges on a single vane in same direction at a velocity of 20m/s. If B2 = 1600 and friction losses over the vane are such that v2 = 0.8v1, calculate the force exerted by water on the vane, and its direction. (14 Marks) b. A closed vertical cylinder 400mm in diameter and 500mm high is filled with oil of relative density 0.9 to a depth of 340 mm, the remaining volume containing air at atmospheric pressure. The cylinder is rotated around its vertical axis at such a speed that oil just begins to uncover the base. Calculate the speed of rotation for this condition. (8 Marks) c. A point A on the free surface of a free vortex is at radius 250 mm and height 180mm above datum. If a free surface at a distance from the axis of the vortex, which is sufficient for its effects to be negligible, is 220mm above datum, calculate the height above datum of a point B on the free surface

Casein, a dairy product used in making cheese, contains 25% moisture when wet. A dairy sells this product for $40/100 kg. If requested, they will dry the casein to 12% moisture. The drying costs are $5/100 kg of water removed. Assume that that the dairy has 1000 kg of the original product (wet casein) that will be dried to 12% moisture and then sold. How much dried casein is produced (in kg)?

A 90° elbow in a horizontal pipe is used to direct water flow upward at a rate of 45 kg/s. Another identical elbow is attached to the existing elbow such that the water flow makes a U-turn as shown in the second figure. The diameter of the entire elbow is 10 cm. The elbow discharges water into the atmosphere, and thus the pressure at the exit is the local atmospheric pressure. The elevation difference between the centers of the exit and the inlet of the elbow is 50 cm. The weight of the elbow and the water in it is considered to be negligible. Take the momentum-flux correction factor to be 1.03 at both the inlet and the outlet. Take the density of water to be 1000 kg/m3.
