Two mixers (mixing points) are responsible for promoting a mixture of water, ethanol and methanol in a given chemical process, the mixing points are isolated adiabatically. The diagram below shows the process information. F1 = 10kg methanol/min 21C s F2 = 40kg ethanol/min 20C F4 F3 = 30kg water/min 28C From the energy balance, determine the temperature, in degrees Celsius, of the mixture in the process output stream S
