Jane Newton showed that the rocket thrust can be equated to its mass times acceleration, or more accurately to the time rate of change of momentum. A basic physics book can explain that in detail.

2009-11-05 Gas pressurized vessel:

Russell Assuming ambient temperature, the ideal gas laws indicate that your vessel would contain 0.27 lb of air and would expand to about 6115 in^3 at atmospheric pressure. But the velocity and time

2009-11-04 Aeroplane/ rocket lift:

Soumen You need to study physics as it pertains to Newton's laws. The rocket get thrust in space by expelling high velocity gases out the nozzle. Newton explains how that creates a reaction force and

2009-11-02 Aeroplane/ rocket lift:

Soumen The devil is in the details. But essentially, a wing with the proper shape, angle of attack, and airspeed will develop surface pressures that when integrated equal lift that counters the weight

2009-10-27 Bypass Ratio:

An engine with a bypass ratio of 2 will pass 2 kg/s of air through the fan for every 1 kg/s through the core. If you know the density and velocity of the two exhausts you could compute the thrust as:
