Rocket Equation Calculator :

Enter the rocket equation calculator its Effective exhaust velocity in m/s, Initial mass in metric tons(t), Final mass in metric tons(t), Change of velocity in km/s, and you get the calculator check it.

Rocket Equation Calculator

Rocket Equation formula :

stands for change of velocity ∆v is equal to the product of the effective exhaust velocity  is multibly by the initial mass including rocket weight without propellants m0(kg) in kilogram is  divided by the final mass including rocket weight without propellants mf(kg) in kilogram. Hence the rocket equation calculator formula has been written as,

∆v = ve * In (m0(kg) / mf(kg))

Where,

∆v→ stands for change of velocity

Ve →effective exhaust velocity

M0→ initial mass including rocket weight without propellants in kg

Mf → final mass including rocket weight without propellants in kg

∆v → difference between final and initial velocity

Ve and m0 →the higher velocity you can get.

Examples:

Sums 1:

Calculate the change in velocity? In a effective exhaust velocity is 5,500 km/h, initial mass is 55 t, final mass is 30 t.

Solution :

Effective exhaust velocity = 5,500

Initial mass = 55 t

Final mass = 30 t

∆v = ve * In (m0 / mf)

∆v  = 5,500 * In (55 / 30 )

∆v = 1.0083 km/s.

Sums 2:

Calculate the change in velocity? In a effective exhaust velocity is 5,600 km/h, initial mass is 60t, final mass is 35 t.

Solution :

Effective exhaust velocity = 5,600

Initial mass = 60 t

Final mass = 35 t

∆v = ve * In (m0 / mf)

∆v  = 5,600 * In (60 / 35 )

∆v = 9.600 km/s.
