Acoustics/formulas

So that formulas can be created once and reused, like images, they have been placed into templates.


Acoustics/formulas/Max efficiency

renders as:

\eta_{\max} = 1 - \frac{2}{k_\mathrm{eff} \sqrt{Q_E Q_{m0}}} \qquad \left ( k_\mathrm{eff} \sqrt{Q_E Q_{m0}} \ll 1 \right )


Acoustics/formulas/Ultrasonic Intensity

renders as:

I_{\mathrm{w}max} = \frac{1}{2} ( \omega_5 u_l )_{max}^2 \ \rho_{m\mathrm{w}} \nu_{\mathrm{w}} ( W / m^2)


Acoustics/formulas/Condition

renders as:

Q_L = \frac{1}{k_{eff}} \sqrt{\frac{Q_{m0}}{Q_E}} = Q_{Lopt}


Acoustics/formulas/Electro acoustic efficiency

renders as:

\eta \approx 1 - \frac{1}{1 + k_{eff}^2Q_EQ_L} - \frac{1}{1 + \frac{Q_{m0}}{Q_L}}
