What is the application of Bernoulli theorem?

The only certain application of Bernoulli's Theorem I know is in the Bernoulli's Theorem experiment in college. All other examples are in my opinion a restatement of Newtons Laws, a missinterpretation of results or a failure to fully understand what is physically happening such as in the fallacy that lift in an aerofoil is due to BT. Bernoulli's Theorem is used by the Fire Brigade to calculate velocity and range of different types of fire-fighting equipment. Going hand-in-hand with the Venturi effect, it help to calculate reach and pressure required to obtain that reach during fire-fighting operations. Example: A pump supplies 6kW of energy to the water flowing thorugh a 45mm hose. If the water flows 25m vertically and through a 25mm branch at a rate of 480l/min, use Bernoulli's equation to find pressure at the branch.
