Aquajet app iconQuick guide trough the Aquajet App

Like all other successful construction work, Hydrodemolition requires meticulous planning and preparation.
To make your work a little easier we have created a smartphone app to help you calculate water flow, speed and pressure, and reaction forces.


Aquajet app calculate size

Calculate nozzle size

The first window is where you calculate nozzle size from a given pressure and flow. Type your values into the white fields for pressure and flow and then select the number of nozzles that should be used. Just leave the other fields blank.
The results are displayed in the dashed fields.

Variables

  • Pressure: The pressure from the high pressure pump
  • Flow: The flow from the high pressure pump
  • Different nozzle types to select from:
  • Aquajet ceramic nozzle efficiency factor: 0,98
  • Metal round nozzle efficiency factor: 0,94
  • Metal round nozzle efficiency factor: 0,70
  • Custom nozzle: Activate and select a custom nozzle factor in the Settings menu
  • Reaction force: The reaction force on the tool or the robot
  • Speed of water: The speed of water when exiting the nozzle
  • Power rating: The power required to drive the high pressure pump

 

Aquajet app calculate size

Calculate multiple nozzle sizes

The app also supports calculation of multiple types of nozzles in the same setup, for example a Rotolance equipped with two round nozzles and two fan nozzles is a common setup.
The Custom nozzle field is activated in the Settings menu. This allows you to calculate any brand of nozzle.

 

Aquajet app calculate pressure

Calculate pressure

By selecting pressure in the upper menu bar it is possible to calculate the pressure from a given flow and nozzle. It is also possible to calculate the pressure when using multiple nozzles.

 

Aquajet app calculate flow

Calculate flow

By selecting flow in the upper menu bar it is possible to calculate the flow from a given pressure and nozzle. It is also possible to calculate the pressure when using multiple nozzles.

 

Aquajet app calculate hose

Calculate pressure loss in high pressure hoses

The hose calculation will help you calculate the pressure loss in the high pressure hoses. Type your values into the white fields. The results are displayed in the dashed fields.

Variables

  • Flow: The flow from the high pressure pump
  • Hose length: The total length of the hoses from the pump to the tool that is used
  • Hose inner dia: The inner diameter of the high pressure hose
  • Parallell hoses: The number of parallell hoses from the pump to the tool used. Sometimes it is nessesary to run more than one hose to achive enough flow to the tool
  • Pressure drop: The total pressure drop that is lost in the hoses
  • Speed of water: The speed of water inside the hose
  • Power rating: The power that is lost due to the pressure drop
