I believe this diagram is incorrect. The length ''l'' is indicated as being the height of the plate that is immersed in liquid, when it should be the the length of the plate itself. I'm no expert on this, so would appreciate it if someone could clarify this. Thanks. [[User:Arjiebarjie|Arjiebarjie]] ([[User talk:Arjiebarjie|talk]]) 10:34, 6 November 2009 (UTC) |

I do confirm that this graph is incorrect. 2l should stand for the perimeter of the plate (l can be the width of plate if thickness can be neglected). The height immersed in liquid is only useful if one wishes to correct for buoyancy effects. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/91.86.149.110|91.86.149.110]] ([[User talk:91.86.149.110|talk]]) 19:51, 21 April 2010 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot--> |

Wilhelmy Plate Diagram
I believe this diagram is incorrect. The length l is indicated as being the height of the plate that is immersed in liquid, when it should be the the length of the plate itself. I'm no expert on this, so would appreciate it if someone could clarify this. Thanks. Arjiebarjie (talk) 10:34, 6 November 2009 (UTC)
