The atmospheric pressure on a particular day was measured as 750 mm of mercury. Convert this pressure measurement to Pascal. (Assume the density of mercury to be 13 600 kg/m3 and the acceleration due to gravity is 10 N/kg (ms-2). ​

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
