i. The range of linear measurements
[6 marks]​

Answer 1

Answer:

The uncertainty in the measured value of displacement if the supply pressure is 200 kN/m2 gauge pressure and the back pressure Bourden pressure gauge can be read with resolution of +500 Pa gauge pressure [5 marks] Assume the operating characteristic of the instrument with usual notation as follows: r=1.10 - 0.50 (An/Ao) for 0.4 <r < 0.9
