Very Important: Bernoulli’s equation is only valid for :
incompressible fluids, steady flow along a streamline, no energy loss due to friction, no heat transfer.Application
of Bernoulli’s equation -
Example 1:
Determine the velocity
and mass flow rate of efflux from the circular hole (0.1 m dia.) at the bottom of the water tank (at
this instant). The tank is open to the atmosphere and H=4 m
