推 tigercow:可能是你沒乘上質量題目是給體積不是(m^3/kg) 04/17 22:17
An ideal Otto cycle has compression ratio of 7. At the beginning of the
compression process, P1=90KPa,T1=27度C,and V1=0.004m^3.The maximum cycle
temperature is 1127度C. For each repetition of the cycle, calculate the heat
rejection and the net work production.Also calculate the thermal efficiency
and mean effective pressure for this cycle.Use constant specific heats at
room temperature.
答案 1.03KJ 1.21KJ 54.1percent 354KPa
請幫幫忙 我只有效率跟答案算的一樣 其他得我怎麼算都答案不一樣
