Steady flow energy equation, Civil Engineering

Assignment Help:

If there is steady flow, nothing changes with time. 

1. The properties of the fluid at entry and exit are constant.

2.  The properties of the fluid at any point in the control volume are constant.

3.  dm1/dt=dm2/dt and both are constant.

4. Q and Wx are constant. 

Ecf = Eci and m1 = m2 = m
