  4. Abstract:
  5. The performance parameter uncertainties of turbomachines at different rotational speed were determined by experimental and analytical consideration. The instruments/sensors were located and installed according to the standards for evaluating the performance characteristics of turbine and compressor in a turbocharger laboratory in a wide range of rotational speeds. The comparison of turbine and compressor sensitivity shows that the sensitivity of compressor to 1% shift in the pressure is higher than that for the turbine. Results also show that the sensitivities of efficiency and power of turbine reduce as rotational speed increases. The total uncertainty of turbine and compressor are obtained and results show that power uncertainties of turbine and compressor are lower than efficiency uncertainty. It is found that changing the number of pressure taps from one to four could reduce the predicted efficiency and power uncertainty of turbine and compressor
