OBJECTIVES:

  • Study non-uniform and uniform flows in an open channel and as well to understand the properties of hydraulic jumps
  • In this article, we will introduce dimensional analysis to fluid flow issues
  • To comprehend the working principles of the various Hydraulic Pumps and machines.

UNIT-1
