The figures show the cross-section of an oil pipe with a manometer attached. On the right side of the manometer, the manometer fluid is in contact with oil, and on the left side, the manometer is open to the atmosphere. The oil has a specific gravity of 0.85 and the manometer fluid has a specific gravity of 1.5. What is the gauge pressure at the center of the pipe if hm is 10 cm and ho is 5 cm?
A mercury (specific gravity = 13.6) manometer connected across an orificemeter fitted in a pipe shows a manometer reading of 2 cms. If the manometer liquid is changed to carbon tetrachloride (specific gravity = 1.6), then for the same flow rate of water the new manometer reading will be __________ cms.
Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?
A student wants to find the absolute pressure of water at a point below the surface of water. He has a barometer and a manometer pressure gauge. The barometer reads 1.3152 bar where as the manometer pressure gauge reads 0.3152 bar. What is the absolute pressure? (Assume that pressure at one end of the manometer is atmospheric.)
A Differential manometer is connected at the points A and Bat the centre of two pipes. The pipe A(left limb) contains a liquid of specific gravity = 1.5 while pipe B (right limb)contains a liquid of specific gravity 0.85. The pressure at A and B are .5 kgf/cm2 and 1.2 kgf/cm2 respectively. Find the difference in level of mercuru in the differential manometer. A is 2.5m above B and 5 m above the mercury in its own limb. B is 2.5 m above the mercury level in limb A.
For manometer, a better liquid combination is one having-------
A Closed U-tube manometer has a gas at one end and vacuum at other end, if the height difference of the liquid (density = 10 kg/m3) in the manometer in 5 cm, what is the pressure of the gas?
Working principle of manometer comprises of balancing a coloumn of liquid against the pressure to be measured. Inclined tube manometer is especially used for the measurement of __________ pressure.
A, B, C, E, F and G are six dancers. B cannot dance better than A. A is a better dancer than G. E is a better dancer than C. E cannot dance better than B or G. F is a better dancer than A. Who among these six is the best dancer?

(Peering(A)/Having peered(B)) at each interview subject, the researchers checked for discolouration. One interview subject shrieked upon (hearing(A)/having heard(B)) the interviewer’s comment about “teeth as yellow as sunflowers.” (Refusing(A)/Having refused(B)) to open her mouth, she glared silently at the interviewer. With the market research on Green Teeth (completed(A)/having been completed(B)), the team tabulated the results.
