Usually the stronger the tornado the larger the funnel but this is not always the case.
A few reasons: 1. The spout acts as a throttle on the flow of water...it narrows and restricts the stream. 2. The flow through the funnel is due more to gravity, than to the velocity of the water flowing into the funnel from a hose ....hard to speed up the flow. 3. Turbulence or water circulation inside the funnel will slow and affect the vertical descent of the water through the funnel.
This is a windsock.
The reason the ping pong ball stays in the funnel when you blow in it is because of Bernoulli's Principle. This principle states that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. When you blow in the funnel at a high speed, the pressure around the ball decreases. Then, the pressure from the outside of the funnel (because there is air pressure everywhere) pushes down on the ball at a lower speed, which would mean higher pressure, which causes the ball to stay inside the funnel. Mind you that the bernoulli's principle is based in the wind tunnel or venturri tube and the funnel is an example of a venturri tube, so that would further explain it.
The wheel size does affect its speed.
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.

A "speed" sensor can affect the shifting of the trans.A "speed" sensor can affect the shifting of the trans.
Distance and time do not, in general, affect the speed. Speed, however, can affect distance or time. Distance is directly proportional to speed, time is inversely proportional.
how does temeperature differences affect wind speed
the brakes affect the speed
Speed does not affect the force of friction.
Time does not affect speed. Measures of speed may be changed over different time periods but that is not the same thing.
