Introduction to measurements.Measurement categories-primary and derived quantities, intrusive and non-intrusive methods;Analysis of experimental data- types of errors, uncertainty analysis, propagation of uncertainty; Statistical analysis of experimental data- normal error distributions (confidence interval and level of significance, Chauvenet’s criterion), Chi-square test of goodness of fit, method of least squares (regression analysis, correlation coefficient), multivariable regression, Students’ t-distribution, graphical analysis and curve fitting.Static and dynamic characteristics; System response- first and second order systems and analysis, Measurement of temperature- thermoelectric thermometry, resistance thermometry, pyrometry, liquid in glass, bimetallic and liquid crystal thermometer, temperature sensors for measurement of transient temperature; Measurement of pressure-U-tube manometer, Bourdon gage, pressure transducers, measurement of transient and vacuum pressures.Measurement of volume flow rate- variable area type flow meter-orifice plate meter, flow nozzle, venture meter, rotameter. Measurement of velocity-Pitot static and impact probes, velocity measurement based on thermal effect, Doppler velocimeter, Time of flight velocimeter.
