A refinery that produces 325 kg/h of benzene at 100 C and 1.5 atm uses a water-fed condenser to prepare the benzene for transportation at 30 C and 1 atm. Be sure to indicate all sources of data when answering the following questions. a) Use a hypothetical process path to calculate the enthalpy change for benzene (kW). b) If the cooling water enters the condenser at 25 C and 1 atm, determine the cooling water feed requirement (kg/h) that ensures an outlet cooling water temperature of 75 C. c) Describe the difference between latent and sensible heat.
