So i want to mix 2 different liquid with different temperature on my mixer.
Here is the case :
I have 2 inlet liquid with inlet 1 is 73,3oC and 1 atm and inlet 2 is 116,3oC and 1 atm. I want the mixture of these liquid is 90oC and 1 atm. The mixture temperature when mixer condition adiabatic is 79,6oC.
My question is : how to calculate the LMTD when u have 2 different inlet temperature? Should i use average temperature (inlet1+inlet2)/2 then doing it with the usual formula or there is other formulas to calculate LMTD in this case? Or should i use Tinlet when the condition of the mixer is adiabatic which is 79,6oC?
(I want to find the heat transfer area for jacket heater of the mixer so the temperature of my mixture will be 90oC).
Thanks for your consideration for helping me.
