Q1: In a venturemeter used for measuring the flow ofoil (-0.85) through a horizontal pipeline, the pipe diameter is 2.4 times the diameter at the throat. Connections are made from the entrance to the meter and the throat to a vertical L tube containing mercury If the difference level between the fluids in the U - tube arms is (x +) in em, where S.N. is student serial number.

We are willing to design a simple setup for the lubrication of a rotating rod. To do so, the vertically aligned rotatingrod is approached to a horizontal surface that is covered with oil. The rod approaches the surface, so there is a 0.2 mmof liquid film between the rod and the fixed surface. Suppose that the radius of the rod is 15 mm, and the rod's angularvelocity is 1500 rpm. Determine the power consumption due to the friction.

A differential mercury manometer is used to measure the pressure drop across an orifice meter as liquid benzene flows steadily in a pipe. Sketch this system showing the section of pipe with the manometer and the orifice meter, showing your understanding of what these devices are. a) Taking the benzene to be flowing from left to right on your sketch, sketch the mercury in the manometer making it clear whether the mercury level in the left or the right arm would be higher. b) If this system is to accommodate benzene flow rates leading to pressure drops of up to 3.5 atm, at least how tall must the manometer be (in m)? That is, what is the maximum height difference in manometer fluid levels that needs to be measured?c) If the flowing fluid were to be air instead of benzene, would the mercury level difference in the manometer be larger, smaller, or the same as with the flowing liquid benzene? Briefly explain.

You have a container like the one shown in figure 1 from which you want to extract liquid with the help of asiphon (inverted U-shaped tube). The siphon should be filled initially, but once this is done theliquid will flow until its level drops below opening A. The liquid has a density ?, and anegligible viscosity. Assume that the area of the container is very large compared to the area of thetube and that both the tube at C and the container itself at D are open to the atmosphere. a) Using Bernoulli's equation and comparing points "D" and "C", determine the speed with which the liquid flows in C. b) What is the gauge pressure of the liquid at the highest point (B)? c) What maximum height H can the highest point (B) of the tube have without ceasing to have flow? d) If the liquid of density ? is changed, for one with density ?2 where ? < ?2, will there be any change in velocity at C? If there is any change, write down with which liquid the highest speed is obtained in C, otherwise…
