Let's discuss the next problem:
An unfortunated engineer has one heavy stone that has to be moved a small distance. Thus, he thinks of pushing it away by means of a water jet, pointing it towards stone centre of mass. But he has to types of jet available:
-One has 50 bar of static pressure and 5 m/s of water velocity.
-The other has 10 bar of static pressure and 89.5 m/s of water velocity.
One jet has to be choosen in order to provide the neccesary force to push the stone a short distance, as engineer's boss is claiming all day it has to be done.
What type of jet would you choose?.
