Let's assume that the liquid is alcohol. What other parameters are needed? And one more thing does the conical shape of the front end of the plunger help or basically the result would be the same as with a simple flat plunger?

Hi guys, I'm relatively new to physics, so please bear with me. Let's image we have a cylinder like this, filled with 8760 mm3 of liquid, with a nozzle on one end and a plunger on the other. An explosive charge goes off behind the plunger, releasing 45 joules of energy, and pushing the liquid out of the nozzle. I want to calculate 1. how far will the liquid go, before dispersing into mist? 2. what is the optimal shape and size of the nozzle, to make the liquid go as far as possible? Where do you think should I start? Thanks!
