Question

In the bourdon tube gauge pressure experiment; The following data are sample measurements of gauge pressure (read by the pressure gauge) and the mass loaded?

Piston Dia, m

Total Mass-kg

Gauge reading kN/m2

0.01767

0.998

39

0.01767

1.498

59

Answer questions 6 & 7

6- The theoretical gauge pressure for the mass loaded of 1.498 kg is:

Answer 1

Theoretical gauge Pressure for mass m= 1.498kg is 59.92 kN/m2

And Theoretical gauge Pressure for mass m= 0.998kg is 39 .92 kN/m2

Here Error in the pressure gauge is 0.92

As Pressure showing in the pressure gauge is 0.92 less than that of theoretical gauge Pressure.
