Problem: How much work is done by pressure in forcing 9.6 m3 of water through a pipe having an internal diameter of 13 mm if the difference in pressure at the two ends of the pipe is 3.2 atm?

Solution:

P1 R = 6.5 mm P2

h1 h2

Pressure difference = P1 - P2 = 3.2 atm or 3.2 x 1.01 x 105 = 3.23 x 105 Pa

Net force acting on the water in the pipe = F = 3.23 x 105 x A .......(!) where A = Area of cross section of the pipe

As volume V of water flows out of the pipe, let the water ...
