In this paper, initially, injectionparameters from viewpoint of macroscopic and microscopicin a manufactured model scale liquid fuel micro-motor thatare measured experimentally in Cold-Test and PhaseDoppler Analyzer (PDA) laboratories, are evaluated. Andthen, Uncertainty Analysis (UA) methodologies forexperimental uncertainty assessment are implemented todrive the respective block diagram. The sources ofuncertainty associated with the techniques are presented,and where such data were available, quantitative estimatesof their magnitude are given. Uncertainty analysis resultsthat are taken to spraying parameters show the highaccuracy of experimental test results. This framework is acomprehensive and complete technique that could beimplemented and executed over any set to analyzeuncertainty value, with difference that each set or case studyhas its respective parameters. %U https://jmee.isme.ir/article_46442_b51318c3d9cb5d0ba6bd45548acb8430.pdf
