An infinite plate is moving at a constant velocity of 0.3m/s over a second stationary plate. A thin layer of the liquid with viscosity of 0.65 centipoises and specific gravity of 0.88 separates the moving plate from the stationary plate. The fluid velocity varies linearly with the distance from the stationary plate. If the length between the two plates is 0.3mm, determine: The absolute viscosity of the liquid in s The kinematic viscosity of the liquid stokes The shear stress on the fluid layer A centrifuge bowl with internal diameter of 150mm is turning at 8000r/min is used to separate chlorobenzene, with a density of 1109 kgm3, from an aqueous wash liquid having a density of 1020 kgm3. The free liquid surface inside the bowl is 40mm from the axis of rotation. If the centrifugal bowl is to contain equal volumes of the two liquids, what should be the radial…

5.Some oil is full of the space by two parallel plates. The lower plate is stationary, while the upper one moves parallel to it with a velocity U=2.5m/s due to a force F=98.1N corresponding to a square with length L= 60cm. h=12.5mm. Determine the dynamic viscosity of oil. y → U > F h
An engineer designing a light aircraft is trying to make an estimate of the radius of the propeller needed. The design speed of the aircraft is 69m/s into still air and at this speed experience allows the engineer to assume a propeller efficiency of 0.8. Other analysis shows that a thrust of 9296N must be supplied by the propeller to maintain the design speed. Assuming a constant air density of 1.21 kg/m³, determine the radius of the ideal propeller in m to 2 decimal places. Note: Use the propulsive efficiency equation to find the final downstream speed of the air and check that this makes physical sense before calculating the radius.

As a result of the rotation, the liquid is displaced clearing a circular area at the bottom of the container or radius R/2. Determine the height of the liquid, H, on the cylindrical wall. R/2
Water fills the pipe AB such that the absolute pressure at A is 450 kPa . The inner diameter of the pipe is 55 mm . The density of the water is 1000 kg/m³. Acceleration due to gravity is 9.81 m/s².

In the figure below, the tank containing the water is very large and open to the air, and the pipe through which the water drains is very small. The pipe is not open to the air and the water can be treated as an ideal fluid. Find the speed at which the water is traveling in the pipe.
1 Consider a rapidly rotating (ie, in near geostrophic balance) Boussineq fluid on the f plane. A) Show that the pressure divided by the density scales as Φ ≈ fUL B) Show that the horizontal divergence of the geostrophic wind vanishes. Thus, argue that the scaling W ≈ UH = L is an overestimate for the magnitude of the vertical velocity
Show complete solution: A vessel of volume V, with a constant cross-sectional area of A and a height of H, is initially (t = 0) filled with a fluid having a density of ρ. At a certain time (t > 0), a drain was opened at the bottom of the vessel for the fluid to flow through by gravity. The velocity coming out of the drain is expressed as vout = C0 (gh)1/2 where C0 is a constant, g is the acceleration due to gravity, and h is the height of the fluid inside the tank. Develop an equation for the height h as a function of time t.
