Specific Impulse
I_sp = v_e / g
What it says
How efficiently a rocket uses propellant, expressed as a time.
Symbols
| Symbol | Quantity | Dimension |
|---|---|---|
I_sp | Specific impulse (s) | T |
v_e | Exhaust speed (m/s) | L T^-1 |
g | Gravitational acceleration (m/s^2) | L T^-2 |
Work it out
Enter what you know. No account needed.
Fill in all but one: v_e, g, I_sp are all empty.
