Consider water flowing steadily in a pipe of varying cross sectional area and height as shown in figure. The area of cross section at A&B are 20cm2 and 40cm2 respectively. The velocity of water at point A is 2m∕s. The work done per unit volume as water moves from A to B in J∕m3 is
(Density of fluid =103‌kg∕m3,g=10m∕s2)
