Question

Define the energy equation of a uniformflow system reduces to that of a closed system when all the inlets and exits are closed.

Expert Solution

Step 1

The general expression of the steady flow energy equation can be expressed as,

$u_{1} + P_{1} V + g z_{1} + \frac{{c_{1}}^{2}}{2} + q = u_{2} + P_{2} V + g z_{2} + \frac{{c_{2}}^{2}}{2} + w$ ......(1)

1 represents the state at the inlet of the system and 2 represents the state at the outlet of the system.

Here u represents the internal energy, P represents the pressure, V is volume, z is the head, g is the acceleration due to gravity, c is the speed of the fluid, q is the heat and w is the work interaction.
