Engine Power and speed

[LoSboccacc (OP)]

I can't find it in the academy: is there a way to get the ship speed beforehand, knowing the tonnage and tuning the power?

I mean, it would be convenient to have ships moving all at the same speed, so I'd like to, say, set 6000km/s as a target, and then calculate the required power for different ship sizes, to build the most appropriate engine for each class.

what I'm looking is at an equation like power = f(tonnage, speed) so I can design engines conveniently

(Total Engine Output / Class Size) * 1000.    So a ship of size 250 with a total engine power of 800 would move at (800/250)*1000 = 3200 km/s

Checking the tutorials if you didn't read them is sometimes useful, or re-reading them just in case.   

So if you use either the size of the ship, or the power of a specific engine, you could figure out what size/power output you would need.   
For example, let's say we have a size 200 ship.    We want 600km/s, thus we have an expression : (X/200)*100 = 6000(km/s)
With simple math, we can deduce that X is 1200.    Thus you need 1200 engine power to give a ship size of 200 a 6000km/s max speed.   

At least, I'm pretty sure.    I'm writing this half-asleep.   

(If you want to use tonnage in the expression, each point in ship size is approximately 50 tons, if I'm not mistaken.  )

Edit: A Verrryyyy simple method if you're using speeds that are rounded up to the nearest thousand, (6000,7000,etc) just multiply by the size by the number of thousands, and you have your required power output.  So for example, 6000km/s = 6.  6x200(size) = 1200 output

Simply rearranging the formular into the format you asked for gives.

Total Required Power = (Speed/1000)*Hull Size

Speed in km/s, Hull Size in spaces(partial spaces only count if on a fighter, otherwise round up any partials)
