I want to clarify this because I'm still not sure how to find the mass flow rate, for instance from a rocket. I still puzzled from the formula that describes the mass flow rate which is [tex]\frac{dv}{dt}[/tex]. This the formula that I'm currently looking over but I'm not sure if its this formula to find the mass flow rate which is:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

0 = \frac{[(M - \Delta M)(v - \Delta v) + \Delta Mu] - Mv}{\Delta t}

[/tex]

Then to find the thrust you use this equation:

F_{thrust}= [tex]qV_e + (P_e - P_a)A_e[/tex]

Where q is the rate of the ejected mass flow which I want to find out.

This is where I got the information: http://www.braeunig.us/space/propuls.htm
