how do you calculate velocity from lift equation ?
how do you calculate velocity from lift equation ?
(OP)
guys i remember the lift equation to be
L= 1/2 rho V*V Cl S
i need to calculate V
i have rho i have cl and i have S
and i don't remember how to do that
L= 1/2 rho V*V Cl S
i need to calculate V
i have rho i have cl and i have S
and i don't remember how to do that

v = sqrt(2L/(rho*S*CL))
RE: how do you calculate velocity from lift equation ?
i know what the formula is
airplane mass : 60,000 Kg
acceleration of gravity is 9.81 m/(s*s)
wing area is 105 m*m
density is standard icao value 1.225 kg/m*m*m
and Cl = 0.384
how do i find L from the above.
i think it has to do with finding acceleration (force / mass) and then from that calculating velocity)
but as i got old i don't remember.
any idea ?

the reality is a plane in level flight, so the lift reacts the weight of the plane
