English: Plot of instantaneous efficiency (blue line) and overall efficiency (red line) as percentages of the engine efficiency for a rocket accelerating from rest. The overall efficiency is relationship of rocket energy to energy of consumed fuel: η o v = E E f u e l = m v 2 m f u e l v e 2 = m v 2 ( e v v e m − m ) v e 2 = 1 e v v e − 1 ( v v e ) 2 {\displaystyle {\eta _{\rm {ov}}}={\frac {E_{\rm {}}}{E_{\rm {fuel}}}}={\frac {{m_{\rm {}}}{v^{2}}}{{m_{\rm {fuel}}}v_{\rm {e}}^{2}}}={\frac {{m_{\rm {}}}{v^{2}}}{\left({{e^{\frac {v}{v_{\rm {e}}}}}{m_{\rm {}}}-{m_{\rm {}}}}\right)v_{\rm {e}}^{2}}}={\frac {1}{{e^{\frac {v}{v_{\rm {e}}}}}-1}}{\left({\frac {v}{v_{\rm {e}}}}\right)^{2}}}

This graph image could be re-created using vector graphics as a SVG file. This has several advantages; see Commons:Media for cleanup for more information. If a SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “Average propulsive efficiency of rockets.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
