Question 49
PINAT2 marksNeeds review
In an air-standard Otto cycle, the pressure and temperature of air just before the compression stroke are 200 kPa and 26.85 °C, respectively. The combustion process is assumed to be a constant volume process, where 1.02 MJ/kg heat is added. The cycle efficiency is 50%. The adiabatic index
and specific heat at constant volume
can be considered to be constant during the process (corresponding values taken at the mean cycle temperature).Assuming that the ideal gas law is applicable,
and
kJ/kg-K, the maximum pressure (in MPa) reached during the cycle is __________. (Rounded off to 1 decimal place)Log in to check the answer
