Calculation of Heat Entering and Exiting from Two Mixture of Gases

Question

500 kg/hour of a mixture containing 10wt% methane and 90wt% ethane at 27°C and 1 bar is fed to a mixer. Another mixture, containing 50wt% methane and 50wt% ethane at 77°C at 1 bar, is also fed to the mixer at a flow rate of 300 kg/hr. The mixer operates at 1 bar and 227°C. Calculate the heat entering/leaving the mixer in kJ/hr. Use the sign of Q and determine if the heat is being transferred FROM or TO the mixer. The specific enthalpies of methane and ethane are given in the table below.

Temperature (°C)     Methane Specific Enthalpy (kJ/kg)     Ethane Specific Enthalpy (kJ/kg)
27                                           1199.8                                           1068.3
77                                           1314.8                                           1161.5
227                                         1708.9                                            1504.6

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
