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 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 122.116.10.35
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
