So, you see, if you know the propeller outline and the sort of propeller geometric fully, for
that type of propeller this km can be calculated and you can get the mass of the propeller. One
more quantity we require for propellers. You will appreciate that propeller is a heavy mass at
the end of a supported shaft, which is rotating, so you have a thrust block here providing a
bearing support to the shaft at one end then, there are intermediate bearings, stern ((bland)) at
the end and then the propeller, a heavy mass rotating at a constant RPM
