P5_4 Where’s Wall-E?

Sam J. W. Waters, Thomas J. Benham, Ben Foxcroft, Chris J.C. Dodds


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.
