Drone spraying system

I'm building a drone with a small spraying system for a school project. It will used for spraying disinfectants. I know I'm gonna need a tank (500ml), a water pump and some tubes and nozzles. What other components do I need to build the sprayer and how do I build it? Any help would be really appreciated. Thanks!

    • Hey, thanks for the reply! So you recommend that I use 2 of those pumps? I have an F450 drone, 920kv 9" props, it's only a medium sized drone so I don't think it will be able to carry a 1 liter container. It's only for a school project, so I just have to show that the spraying system works.
      • try with 1 pump first. 3-4 nozzle will be OK. More nozzles, less pressure, maybe 2nd pump need. Me I can control left-right independent, with different solution if i want, i have 2 containers. Send your pictures when your setup is ready.
        • Is it a good idea to use just 1 nozzle for a 240L/H pump? I need the high pressure. I'm not sure if using 1 nozzle is going to create too much pressure and potentially damaging the pump.
          I have a Turnigy receiver controlled switch https://hobbyking.com/en_us/turnigy-receiver-controlled-switch-1.ht... which will be connected to pump and receiver.
