Question

In a horizontal pipe line of uniform cross section as pressure falls between two points separated by certain distance, the change in the kinetic energy of the oil flowing between these two points is 0.01 JKg to the power of negative 1 end exponent and density of the oil is 800 Kg cubed. Then the fall in pressure between those two points is

  1. 2 Nm to the power of negative 2 end exponent
  2. 4 Nm to the power of negative 2 end exponent
  3. 6 Nm to the power of negative 2 end exponent
  4. 8 N m to the power of negative 2 end exponent

The correct answer is: 8 N m to the power of negative 2 end exponent
