CALCULATION OF EFFECTIVE AREA BASED ON DIMENSIONAL MEASUREMENT FOR 35 mm DIAMETER PISTON-CYLINDER UNIT OF KIM-LIPI PRESSURE STANDARD

• Abstract:

  The calculation of KIM-LIPI 35 mm diameter piston-cylinder effective area, based on the dimensional measurement has been done successfully. This effective area was calculated by using simplified formula and simple numerical analysis. The purpose is to get a smaller uncertainty as the source of traceability chain for pressure in KIM-LIPI. The both result shows good agreement and only differ 0.6 × 10^-6 relatively and it is consistence compare with the result based on crossfloat with relatively less than 2 × 10^-6.
