Amillimeter of mercury (mmhg) is a unit of pressure defined as the additional pressure generated by a column of mercury one millimeter high. if ρhg = 13595.1 kg/m3 and g = 9.80665 m/s, how many pascals is 1 mmhg worth? how many pascals is an inch of mercury (inhg) worth?

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
