3D fluids generally need more particles, and the amount of neighborhood of each particle is also much larger. Also, 3D rendering is much more expensive than simple 2D rendering as it has to deal with scene depth testing and accurate light absorption.
We've been able to simulate around 1000 particles in 2D in an iPhone 4S @ 60 fps, around 1800 in an iPhone 7 (2D too). The amount of 3D particles had to be kept below 700 for acceptable performance. Whether or not this is enough for your purposes depends on the amount of detail you need in the fluid.
Many more parameters affect the performance: fluid compressibility, simulation timestep, etc. So it depends a lot on the specific details of your use case.
Could you show an example of 2D? How visually it looks so that I can understand. We will just have a 3D glass in which you need to pour the liquid, visually it will be like 2D. And another question, can we increase the size of the particles so that not a small jet is, but larger?
