7000 lb/hr of aniline is to be heated from 100F to 150F by cooling 10000 lb/hr of toluene with an initial temperature of 185F in 2by 1 inch. IPS double pipe hairpin exchanger 15ft long. pressure drop of 10psi is allowable and a dirt factor of .005 is required.what is the final dirt factor.
You have to calculate the heat duty from the amount of heat it takes to heat the 7000 pounds of aniline from 100 to 150 degrees F. Without the heat duty you can not calculate the final temperature of the toluene. You should be able to get the information you need in terms of specific heat online.
