In tank cleaning, which factor most directly affects the energy of the cleaning jets?

• A. Time to rotate through all angles
• B. COW material
• C. Pressure supply
• D. Area shielding

Answer: (C)

The key idea is that the energy in each cleaning jet comes from the hydraulic pressure pushing the liquid through the nozzle. The jet’s exit velocity—and thus its impact energy on residues—rises with higher supply pressure. In simple terms, the cleaning power of the jet is tied to how much pressure you push through; the higher the pressure, the faster the liquid exits and the more energy it carries to dislodge deposits. Time spent rotating through angles just affects coverage and how long a surface is exposed, not the jet’s energy per se. The material used in a COW system mainly influences chemical action, not the mechanical energy of the jets. Area shielding can alter how much jet energy actually reaches a target by blocking or deflecting spray, but the fundamental energy comes from the pressure supply. If you double the pressure, the exit velocity and the jet’s energy increase accordingly, roughly following the square-root relationship with pressure, which illustrates why pressure supply is the direct driver of jet energy.
