Default static pressure in water wheel

Hy everybody.

I am simulating a water wheel with an angular velocity v [rad/s].

If there is no water, the static pressure is only due to the air weight, so it increases from the top of the wheel toward the lowest point of the wheel (since the air is lightweigh the difference of static pressure has to be small, but if I plot it the difference is 300 N/mq!! And the wheel is only 2 m in diameter.

Anyone can help me?
Thank you
