A siphon is a convenient device for removingliquids from containers. To establish the flow, the tube must be initiallyfilled with fluid. Let the fluid have density r, and let the atmosphericpressure be patm. Assume that the cross-sectional area of the tube is thesame at all points along it. (a) If the lower end of the siphon is at adistance h below the surface of the liquid in the container, what is thespeed of the fluid as it flows out the lower end of the siphon? (Assumethat the container has a very large diameter, and ignore any effects ofviscosity.) (b) A curious feature of a siphon is that the fluid initiallyflows “uphill.” What is the greatest h
A thin plate is separated from two fi xed plates by veryviscous liquids μ 1 and μ 2 , respectively, as in Fig. .The plate spacings h 1 and h 2 are unequal, as shown.

The belt in the Ögure moves at steady velocity V and skims the top of a tank of oil having viscosity. (a) Develop and expression for the required belt drive power in terms of h, L, b, V , and . Recalthat, for steady motion, power is equal to force velocity.(b) What power is required if the belt moves at 5 m/s over SAE 50W oil ( = 0:86 kg/ms) withh = 2 cm, L = 2 m, and b = 0:5 m
plzz help meeeeeeeeee The belt moves at a steady velocity V and skims the top of oil tank. Assuming a linear velocity profile in the oil, what is the required belt-drive power P (watt) (P= power = force x Velocity) if the belt moves at 3.5 m/s over oil with specific gravity of S=3.6 and oil viscosity of 0.004 m2/s. Belt geometry L= 2 m, b = 60 cm, and oil depth is h = 3 cm?
The bottom quarter of a vertical cylindrical tank of total height 0.4 m and diameter 0.3 m is filled with a liquid (SG > 1, like glycerin) and the rest with water, as shown in the figure. The tank is now rotated about its vertical axis at a constant angular speed of ω. Determine (a) the value of the angular speed when the point P on the axis at the liquid-liquid interface touches the bottom of the tank and (b) the amount of water that would be spilled out at this angular speed.
Determine the force required to drag a thin plate placed in themiddle of two parallel plates 24 mm apart with the space filledwith a fluid of viscosity 0.82 Ns/m2. The area of the plate is 0.5 m2and the speed at which it is dragged is 0.6 m/s. Also find the force ifthe thin plate is at 8 mm from one of the plates.
Two small vessels are connected to a U-tube manometercontaining mercury(relative density 13.56) and the connectingtubes are filled with alcohol (relative density 0.82). Thevessel at the higher pressure is 2 m lower in elevation than theother. What is the pressure difference between the vessels whenthe steady difference in level of themercury menisci is 225 mm?What is the difference of piezometric head? If an inverted U-tubemanometer containing a liquid of relative density 0.74 wereused instead, whatwould be the manometer reading for thesame pressure difference?
