Answer 1

Answer on Question #59434-Physics-Molecular Physics-Thermodynamics

State the steady flow energy equation and mention all the variables used and their corresponding standard SI unite.

Answer

The steady flow energy equation is

$$q + w _ {s} = \frac {1}{2} (c _ {2} ^ {2} - c _ {1} ^ {2}) + g (z _ {2} - z _ {1}) + (h _ {2} - h _ {1}),$$

where $q$ is heating per unit mass $\left[\frac{J}{kg}\right]$, $w_{s}$ is the shaft work per unit mass $\left[\frac{J}{kg}\right]$, $g$ is the acceleration due to the gravity $\left[\frac{m}{s^2}\right]$, $h_2$ and $h_1$ are the specific enthalpy at points 2 and 1 $\left[\frac{J}{kg}\right]$, $z_2$ and $z_1$ are the height at points 2 and 1 $[m]$, $c_2$ and $c_1$ are the velocity at points 2 and 1 $\left[\frac{m}{s}\right]$.
