The thrust is determined by the mass flow multiplied by its increase in velocity:
F = m * V.
This should be:
F = m * a
where 'a' is the increase in velocity (meters per second per second).
The power required to attain the propulsion is given by the formula:
P = ½ * m * V^2
F = Newton
m = mass flow (kg per second)
V = increase in velocity (meters per second)
P = power (Watts = volts * ampere)
This one should be:
E = ½ * m * V^2
where E is the energy (in Joules or kg m^2/s^2), and V is the velocity (in meters per second), <u>not</u> the increase in velocity, and m is the mass (in kg).
The formula for power is:
P = F * V
Where P is the power in Watts, F is the force (thrust) in Newtons, and V is the velocity in meters per second.
