I compared some in-game sampled ∆Vs with calculated ∆Vs (using the [http://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation rocket equation]) on a low mass orbiter (w/3 thruster blocks) and found that my sampled values were on average 4.3% higher than the calculated values.  If I used a mass of 0.005t (for example, instead of the stated mass of 0.05t), the values only differed by 0.06%.<br>

I have the stock v0.23.5, w/no mods, and I'm not sure if there is a way I can check the actual value the game is using. Any thoughts on this?--[[User:BlobKerman|BlobKerman]] ([[User talk:BlobKerman|talk]]) 09:40, 31 May 2014 (CDT)
 
:Well, I answered my own question.  I put another orbiter up with an additional 60 thruster blocks (nearly doubling the mass of the orbiter), and did a 34 second burn, garnering the same ∆V (2250.8 m/s) as the first orbiter, and ~equal to the calculated ∆V (2251.6 m/s), '''assuming the thruster mass is zero'''.  (With the nonzero 0.05t amount, the calculated ∆V of the 2nd orbiter is 1130.5 m/s.)  It seems like a mistake to not note this on the page, or its part-template.
 
:EDIT: Duh, it says it right on the page, "The part now has 0 mass and drag, despite the listed values."  I still think it should be included in the parts-template.--[[User:BlobKerman|BlobKerman]] ([[User talk:BlobKerman|talk]]) 12:58, 31 May 2014 (CDT)
