I conect that tube of 1*1m with another tube of 1m long and 0.5m wide and this connected to another tube of 1 m and 0.25 m wide and so on

So i have a tube in which every 1 m of length the wideness of the tube is half, 1m. 0.5, 0.25, 0.125... and so on

The fluid starts with a speed of 1 m/s and a pressure of 1 bar, when it goes to the next part of the tube the speed doubles and the pressure halfs because the section is half

So as the ideal fluid goes along the narrowing tube every meter doubles the speed and halfs the pressure

So the pressure will go: 1 bar, 0.5, 0.125 and so on and the speed of the fluid will go: 1m/s, 2, 4 ,8 ,16 ,32,...

So with a presure of 1 bar and a initial speed of 1 m/s i can get an ideal fluid to go as fast as i want

So can someone explain me what's wrong with this assumption because kinetic energy can't be created

This is a thought experiment with an ideal fluid so please don't tell me it wouldn't be posible because of friction, its an ideal fluid
