01 Intro
Pressure¶
\[ \begin{aligned} P &= \frac F A \\ &= \rho g h \\ P_\text{abs} &= P_\text{atm} + P_\text{gage} \\ &= P_\text{atm} - P_\text{vac} \\ 1 \text{ bar} &= 100 \text{ kPa} \end{aligned} \]
Manometer¶
Denser fluid will be below
\[ \begin{aligned} P_\text{a} &= P_\text{b} \\ P_{g_1} + \rho_1 g h_1 &= P_{g_2} + \rho_2 g h_2 \end{aligned} \]
Terms¶
Term | Meaning |
---|---|
Specific Gravity | SG = \(\frac \rho { \rho_\ce{H2O} }\) |
Cycle | Initial and final properties are the same |
Steady Flow | Properties are independent of time |
Uniform Flow | Properties are independent of location |
