Specific Impulse Calculator -Irfan Mujawar

Specific Impulse Equation

It is the total impulse (or change in momentum) delivered                      per unit of propellant consumed and is dimensionally                            equivalent to the generated thrust divided by the propellant                    mass flow rate or weight flow rate.If mass (kilogram,                             pound-mass, or slug) is used as the unit of propellant, then                     specific impulse has units of velocity. If weight (newton or                     pound-force) is used instead, then specific impulse has units                 of time (seconds). Multiplying flow rate by the standard                         gravity (g0) converts specific impulse from the weight basis                   to the mass basis
