Sample problems:
1. A liquid (sp gr 2.0) is flowing in a 50 mm diameter pipe. The total energy at a given
point is found to be 75 J/kg. The elevation of the pipe above the datum line is 3 m,
and the pressure in the pipe is 65.5 kPa. Compute the velocity of flow and the
horsepower in the stream at that point.
