How can we write Bernoulli's principle derivation in short?

Hi Sowmya!
 
Bernoulli’s Principle:

The sum of pressure energy, kinetic energy and potential energy per unit mass is always constant for the streamline flow of a non-viscous and incompressible fluid.
Given figure shows a section of a streamline flow:
With reference of variavles in the given figure,
Hope it is useful to you!
Cheers!!
