DIF means Dynamics of Inmcompressible flow. In this subject you will learn about fluids and its properties, this subject is quite easy and very important for mechanical engineers, this subject is base of hydraulic machines.
You have learned in 11-12 science about fluid and its some basic characteristics like viscosity, surface tention, cavitayion, vapour pressure, the same will revised here.
