Have a look at this incredibly-realistic wet floor simulation shared by the developers of FLIP Fluids, a popular Blender add-on for setting up, running, and rendering fluid simulations directly in Blender.
Created with Poly Haven's free Abandoned Factory Canteen 02 HDRI and Wet Floor Sign 01 model, the simulation was modeled to scale for accurate speed and motion and utilizes Blender Cycles' default motion blur settings. According to the creator, the 1400 frames of the animation took around five days to render at 1080p on a GTX 1070 GPU.
