What is the temperature at the condenser outlet?

A stream of pure cyclopentane vapor flowing at a rate of 1.55 m3/s 150 â—¦C and 1 atm enters a cooler in which 55% of the feed is condensed at constant pressure.

(a) What is the temperature at the condenser outlet? Explain how you know (a single sentence should suffice).

(b) Prepare and fill in an enthalpy table (of flow and enthalpy of each stream, based on the assumed standard state) and calculate the change in enthalpy ∆H = Hout − Hin.
