In this experiment we are going to measure the pressure of gage and absolute by using a dead weight device which it use bourdon tube to measure the pressure.
We are going to explain the way of this experiment :
1- Bring the dead weight device and take the data's about the device as radius and pressure when no weight is applied . 2- Start putting the loads on the device starting it with 0.5 kg and increasing linearly by 0.5 kg for each step until reach 3 kg . 3- Begin taking readings from the pressure gage reader of the bourdon tube which its by bar . 4- Tabulate the data in a tablet and draw graph.
Results and discussion:
The given data it's taken in advance :
W free= 1kg , d=2 cm , R=1 cm , A=0.000314159 m2, and the reads are in the tablet below : error٪
| P cal (bar)
| Pavg (bar)
| P+ ( bar)
From data's above we can see that by increasing the load the pressure will increase linearly.
Now we will see the graph which it describe the relation between the P cal and
Pavg (bar) , the graph is below :-
now from the graph above we can see that the y axe is considered as Pcal and the x axe is considered as P avg .
As seen above we found that by increasing the loads in the piston of the device the pressure will increase , and by increasing the calibration pressure the average pressure will...
