Questions tagged [lox]
LOX (liquid oxygen) is pure oxygen kept at a temperature at which oxygen is a liquid, between approximately 54.4 K and 90.2 K (corresponding to -219 °C to -183 °C, or -362 °F to -297 °F). LOX can be used as an oxidizer in liquid-fuel rocket engines.

Propellant Density Calculation for LOX/Kero
I am trying to make sense of the equation for propellant density calculation, rho=(rw-1)/(rw/bo+1/bf).
Sutton, 7th edition, gives this equation (7-2) as:
$ \ \ \ \rho_{av} = \frac {\rho_o\rho_f(1+r)} {...
