for the MESH equations for a heat exchanger with an inlet and an outlet stream. Two components should be considered (water and Mwthanol). How many equations are there, how many unknowns?
Sir! What happened if we don't know one of the outlet temperature of fluid ( eg: outlet temperature of oil ) then how to find specific heat capacity for oil along with how to find the outlet temperature of oil ?
As for as I understand this will be done on assumption but I'm not understanding the proper way of assuming outlet temperature of oil.. Sir could you plz help me to figured out how to assume any outlet temperature of fluid?
You can use the cold fluid( water) to find of hot fluid(oil) as the heat losed on the hot side is the same as heat gained on the cold side, you can equate the "Q"s to find the Temp of the other side😜
While finding the Reynolds number, isn't all the cases where to include the number of tubes "n" and number of passes?
Thank You! I did not understand how to use the chart.
Why did you insert the inside diameter in the ln expression of the total resistance

thankyou
What if my R is zero?? Then what is the value of my F ??
