A continuous gravity decanter is used to separate two immiscible liquids, oil (SG = 0.76) and water. In the decanter, the water takes up a height of 0.75m, then a 0.4-m layer of oil settles on top. At what height must the overflow line be placed? O 1.05 m 1.72 m 0.64 m 3.49 m
QI/ Determine the velocity of a plate which was lifted upward, if the force required for lifting it is 272.246 N and its weight is 90 N. This metal plate which its dimensions are 1.25 m x 1.25 m × 6 mm thick is placed midway in the 24 mm gap between the two vertical plane surfaces as shown in the Fig. below. The gap is filled with an oil of specific gravity 0.85 and dynamic viscosity 3000 mN.s/m². Vertical Plane Oil 6 mm -24 mm Plate
A 80 cm tall cylinder is filled with water (ρwater = 1000 kg/m3) and oil (ρoil = 600 kg/m3) and is capped on the bottom so no fluid is flowing. It contains equal amounts of the two fluids by weight. What is the pressure at the bottom of the cup?
A 45 grams (0.045 kg) golf ball of diameter equal to 43 mm fell into a 2m deep lake. Neglect inertia at the moment of impact. Assume viscosity of 1.12x10-3 Ns/m2 , water density of 1,000 kg/m3 and Cd=0.5. Sphere volume equals 4π r³ /3. 1. How long will it take from the moment it hits the surface until it gets to the bottom? 2. If one estimates the Cd with Cd=24/Re formula, the settling velocity would be unrealistically large. Why?

Find the force required to pull a shaft with diameter D, steadily into a sleeve with diameter D, and length L at a velocity of V. The clearance between the shaft and the sleeve is filled with an oil of viscosity μ.
One end/side of the pipe is positioned on level (h1) and the other is tilted upward at a height h2.The pressure values of fluid within this pipe, both on level and up, are measured as P1 and P2.If the fluid flow is kept at constant speed,use Bernoulli’s principle to show that pressure of the fluid inside the pipe tilted upward, P2, is given by: P2=P1 -ρgh2
