P5_4 Where’s Wall-E?

We have calculated that a fire extinguisher under incompressible flow has a ∆ v = 4 . 1 ms -1 and a ∆ v = 8 . 4 ms -1 under adiabatic flow. If Wall-E was to use fire extinguishers as a method of propulsion in space rather than NASA’s MMU (with ∆ v = 25 ms -1 ) he would require 10 fire extinguishers for incompressible flow and 4 for adiabatic flow.
