Power of a blower fan is a combination of its static pressure and air volume flow. So as water pump power is head and volume, electricity power is voltage x ampere.

In fact, all power has these 2 components, intensity and consistency. The power of hot water to hurt you is a factor of its temperature (intensity) and amount (consistency). Power of your determination to succeed is intensity and consistency of your effort.

In this sense, static pressure is intensity, airflow is consistency.
