Question

A steady flow of water passes along a horizontal tube from a wide section X to the narrower section Y, see figure. Manometers are placed at P and Q at the sections. Which of the statements A, B, C, D, E is most correct?

  1. water velocity at X is greater than at Y    
  2. the manometer at P shows lower pressure than at Q    
  3. kinetic energy per m to the power of 3 end exponent of water at X = kinetic energy per m to the power of 3 end exponent at Y    
  4. the manometer at P shows greater pressure than at Y    

The correct answer is: water velocity at X is greater than at Y

An open-ended U-tube of uniform cross-sectional area contains water (density 1.0 gram/text  centimeter  end text blank to the power of 3 end exponent text  ) end text standing initially 20 centimeters from the bottom in each arm. An immiscible liquid of density 4.0 grams/ centimeter3 is added to one arm until a layer 5 centimeters high forms, as shown in the figure above. What is the ratio h subscript 2 end subscript divided by h subscript 1 end subscript of the heights of the liquid in the two arms?
