Bernoulli's principle basically states that when there is a decrease in pressure there must be an increase in velocity at the same rate that the pressure was decreased.
An everyday use of this would be a fire hydrant. If you pry it open releasing a huge amount of water, for about 20 minutes the water is steadily streaming out wetting everything that it can in its path. After these 20 minutes the water isn’t being projected as far as it was in the beginning, meaning that it has lost its pressure. As time goes by, the pressure at which the water was coming out has gone down, but the velocity at which the water was coming out has increased rapidly. This is an example of Bernoulli's principle.
