AiR is to be compreesd reversibly from an initial condition
: of 1 atm and 60(*f) to a final state of 5 atm and 60(*f)
: by three different processes:
: (a)heating at contant volume followed by cooling at constant
: pressure.
: (b)isothermal compression
: (c)adiabatic compression followed by cooling at constant volume
: Air may be considered as ideal gas with Cv=5 and Cp=7(btu)/(lb moa)(*f)
: ,the initial volume=379ft^3 .the final volume=75.8ft^3
: 計算(1)the work required
: (2)the heat transferred
: (3)the change in the internal energy of the gas
: (4)the change in the enthalpy of the gas
: fr the three processes
請問
路徑圖如何畫...
想了蠻久了...
我只劃出兩種...可是解起來怪怪的
可以請高手話給我看一下嗎...
謝謝
