Gauging Thrust Figures

[KJ_Lesnick]

I'm wondering if there's any mathematical formulae for either determining precise static non-afterburning thrust levels, or at least good guesstimate figures based on the following parameters

• Engine inlet-diameter
• Mass-flow
• Pressure-ratio
• Ratio of inlet to nozzle diameter
• Other

Since I'm not a propulsion engineer, nor am an the best at math, I do effectively need to know what units to enter in (i.e. metric and things of that sort).




BTW: Everybody tells me to do my own research and this will help me do exactly that without having to pester everybody
