Density of gauge fluid used in well manometer is rho =13600 ±13.6 kg/m3. the maximum height of gauge fluid in the reading scale is h=0.4 m., and uncertainty in reading scale is ± 0.1 mm. compute the absolute uncertainty and accuracy of this well manometer? use g = 10 m/s2 , and one digit after decimal point for results only!

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
