Summary/Abstract:
The main objective of this experiment is to verify the Bernoulli Equation using a Venturi meter which is a converging-diverging tube of known geometry which is attached to a pipeline to help measure different quantities of flow rates. Furthermore, different forms of Bernoulli’s Equation is used to calculate pressure head, head loss and velocity loss. After finding out the data, the measured values of the static pressure head for each increasing flow rate is compared with the theoretical value, calculated by the Bernoulli’s equation. The head loss is also found by measuring the 8th manometer on the manometer panel whose difference each time will give the head loss. The difference between the measured and theoretical value of static head is then found out to be due to the frictional losses
