provide solution of example 7.4

7.4. 43,800lb/hr of 42API kerosene between 390 and 200F is used to heat 149,000lb/hr of 34API Mid-continent crude from 100 to 170F in a 662ft2 exchanger (Example 7.3). The clean coFrg. 7.26. Illustration for Prob. 7.3. efficient is 69.3Btu/(hr)(ft2)(F). When the 1-2 exchanger is clean, what outlet temperatures will be obtained? Calculate the outlet temperatures directly from FT. How does the total heat load compare with that which could be delivered by a true counterflow exchanger assuming that the same U could be obtained
