Good idea, I will look for some popular slides and estimate the velocity, thanks!

Sure I have contacted some companies to know that kind of details and I have hardly received any response... it's a shame. I'll bet for the range you advised me, thanks.

Hi! Does anyone know what drag coefficient has a person in a water slide? I've only found for full vertical/horizontal body, but not for a person in a water slide, considering it has a slope. Related to that, the cross area of a person can be calculated? Thanks.

So maybe I've been focusing in the relationship between the water flow and the water depth with the user's speed, while I should have been focusing in the air effects, since you adivsed me to neglect water friction effects in terms of calculations. Guess I will try to limit the terminal...

Hi again, thank you all of you for responding my post. I don't know if I get the main ideam but what you all seem to agree is that I should apply the basics of physics, meaning the formulas like: x=xo+vo*t+0.5*g*t^2 and v=vo+gt? Then, the mass of people and their area aren't a variable that...

So the speed is more related to the slope than the water flow? But it's still related to water flow in some way, isn't it?

Yep, I thought about the Newton viscosity law, that links the velocity with the water thickness. But that thickness is the one beneath the person, so its like 0,01 mm (logically). My idea is to know the flow in order to not exceed the maximum velocity, which is 14 m/s.

Thank you for responding. Actually I'm trying to calculate the speed of a person in a water slide, in particular the descending speed in a slope. I guess the person speed is related to the water flow and the degree of the slope, but I was asking for any formula that relate both. Hope I could...

Hi! I'm currently doing a project to simulate a water slope, and want to find the maximum speed of a person going downhill in function of the water flow. At first I thought using a combination of the Manning equation and the Newton Law for viscosity, through the sheet of water, but I'm in a dead...
