Work Done by Pumping a Fluid

Let’s start by looking at the weight of a volume of water:

   Weight = specific weight * volume = s.w.*v

For water at room temperature, the specific weight is 62.4 lb/ft3 or 9800N/m3.

   EXAMPLE: If a material has a specific weight of 10gr/cc, find the weight of an object produced by rotating the area bound by y = 3-x2 x=0 and y =0 about the y-axis if x and y are in centimeters.
