Calculations for backflowing a 55-gallon of drum of deadly contaminates
into the Hillsborough County public drinking water supply
in less than two minutes!

Less than two minutes is required for a terrorist to over-pressure 55 gallons of watery chemical or bio-toxin contaminates back through a Dual Check valve into the County's public drinking water system using cascading SCUBA tanks as a pressure source and allowing for Boyle’s Law. The calculation page below shows over 30 gallons per minute, so two minutes would be over the contents of a 55-gallon drum. Since Double Check valves are near the street, the drum could remain in the vehicle with a hose to feed the contaminate from the drum into the Double Check value. Easy as pie!
