This formula was given to calculate the total energy. The velosity head is also in meters. As i said before the height of fluid in piezometer tube is equal to p/ρg or pressure=hρg so we have head of fluid in meters plus head of velosity in meters.v²/2g gives meters. m²/s² χ s²/m = meters. My...

The formula we use is that P/ρg + v²/2g +z=total energy P/ρg= head of fluid v²/2g = head of velocity

head of fluif plus head of velosity = total energy . The experiment is horizontal.

I can sent my excel file, the problem is that i have to explain how is that possible. Only if there was back pressure would cause an increase in head of fluid and conseqently the total energy.

Homework Statement Hi I have done an experiment applying the bernoulli equation on a venturi tube, according to bernoulli the energy must remain the same. However according to my calculation the energy increases when the tube contracts up to the point of the throat. Can someone explain how...
