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 780 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. The gas constant of air is R = 0.287 kJ/kg·K. Take into account the variation of specific heats with temperature. Determine

a. the pressure and temperature at the end of the heataddition process.
b. the net work output.
c. the thermal efficiency.
d. the mean effective pressure for the cycle.

Explanation:

Although butter is high in calories and fat, it contains a variety of important nutrients as well. For example, it's a good source of vitamin A, a fat-soluble vitamin needed for skin health, immune function, and healthy vision

If the temperature goes on increasing with respect to the length (i.e temperature gradient)then it is called positive heat transfer. If the temperature gradient decreases then it is called negative heat transfer.
