Leaky bucket illustrating water pressure and depth. The rate at which water flows out of the hole depends on how full the bucket is. The fuller the bucket, the greater the water pressure forcing water out of the hole. Since there are 3 holes in this bucket, the pressure is highest at the bottom forcing the water out with greater force than the top hole.
