MEASUREMENT UNCERTAINTIES Clause Samples

MEASUREMENT UNCERTAINTIES. For each one of the parameters, the uncertainties of the measurements required to calculate the parameter will be accumulated as per their percentage impact in calculating the total uncertainty of the parameter tested. In case of measurement uncertainties of parameters with correction curves, the percentage uncertainties will be determined by the percentage impact of the uncertainty on the measured parameter according to the correction curve. The resulting accumulated percentage uncertainty is applied to the parameter tested, determining the Measurement Uncertainties of each parameter. Z1 - Uncertainty factor of the electrical meter reading [ *** ] Where: [ *** ] Z2 - Uncertainty factor of the Facility net power. [ *** ] Where: Performance Test - Raft River EPC Contract, Exhibit D Rev 0 – 12/05/05 [ *** ]

MEASUREMENT UNCERTAINTIES. Z1 Uncertainty factor of the electrical meter reading. Z1 = [1 +/- Umem/100] Z3 Uncertainty factor of the Net Energy measurement ------------------------------ Z3 = 1 +/- \ | U12 + U22 + U32 + U42 + U52 / 100 \| Where: U1 Effect of stream 1 brine flow measurement uncertainty in percent change in Correction Factor per percent measurement uncertainty U2 Effect of stream 1 brine inlet temperature measurement uncertainty in percent change in Correction Factor per measurement uncertainty (in deg. F) U3 Effect of stream 2 brine flow measurement uncertainty in percent change in Correction Factor per percent measurement uncertainty U4 Effect of stream 2 brine inlet temperature measurement uncertainty in percent change in Correction Factor per measurement uncertainty (in deg. F)
