Fluid measurement devices:

What is the principle on which the fluid measurement devices in our lab are based? Use simple sketch to illustrate your answer.

 

 

 

 

 

 

 

 

 

 

 

 

 


 

Centrifugal pump

 


Use this figure to explain how the pressure increases in a centrifugal pump? Follow the fluid as it comes from the tank until it reaches the discharge.

 

 

 

 

 

 

 

 

 

 

 

Compressible flow in convergent divergent nozzle:


Draw the pressure and velocity distribution inside a nozzle in (a) venture mode and (b) operation mode.

 

 

Pelton wheel experiment:

We performed together the Pelton wheel experiment. The following data is given:

It took 59 seconds to balance 10 kg weight. The pressure reading was 37922.5Pa.
