# What is the water pressure at the bottom of the channel? How to calculate? [duplicate]

Suppose that in a spacecraft, water flows along a circular channel, the distance from the bottom of the channel to the axis of the circular channel is r, the width of the channel is b, the depth of the channel is h (water depth is also h), the density of the water is ρ, the angular velocity of the water is ω, no viscosity, no friction, no water tension, and the air pressure of the spacecraft is one atmospheric pressure.
