heat exchanger

[tarek12]

I have to make a heat exchanger calcul after a change in the density of crude oil
i will use KERN method , i have somme questions
whene i calculate Q= mCp (t2-t1)
1/about Cp wich Cp i have to take Cp of t1 or Cp of t2?
2/ how i can know if the heat exchanger is wroking correctly and if results are good or no?
3/ now we have a production of 90000m3/day and we want to calculate if the heat exchanger could work if we increase the production to 200000m3?
NB : we have a tubulair heat exchanger
thank you!!
