Question

A steady stream of water falls straight down from a pipe as shown. Assume the flow is incompressible, then

  1. the pressure in the water is higher at lower points in the stream    
  2. the pressure in the water is lower at lower points in the stream    
  3. the pressure in the water is the same at all points in the stream    
  4. pressure variation will depend upon density and exit speed of the water    

The correct answer is: the pressure in the water is the same at all points in the stream


    Pressure at all points in stream will be atmospheric.

    A square box of water has a small hole located in one of the bottom corner. When the box is full and placed on a level surface, complete opening of the hole results in a flow of water with a speed V subscript 0 end subscript, as shown in figure (A). When the box is still half empty, it is tilted by 45 to the power of 0 end exponent so that the hole is at the lowest point. Now the water will flow out with a speed of
