In a horizontal pipe line pressure falls by 10pa between two points separated by a distance of 1km.The change in the kinetic energy per kg of oil when the oil flows from one point to the other is(density of oil=800kg m-3
Hi Spandana,
We are going to solve this question by using Bernoulli's equation.
p1V - p2V = (1/2mv2)square - (1/2mv1)square
that is, Delta pV = Delta E
So, Delta Eo = Delta E/m =Delta pV/m = Delta p/ m/V = Delta p / p(density) = 10/800 = 1/80 = 0
After solving this equation we will get the answer => Delta Eo = 0.0125 j
