A Stream of ethylene glycol vapor at its normal boiling point and 1 atm, flowing

Question

A Stream of ethylene glycol vapor at its normal boiling point and 1 atm, flowing rate of 175kg/min is to be condensed at a constant pressure. The product stream from the condenser is liquid glycol at the condensation temperature. (A) The Rate which heat must be transferred (Q) was calculated to be 2814.7 KW.

(B)If heat were transferred at a lower rate than that calculated in part (A), what would the state of the product stream be? (Deduce as much as you can about the phase and the temperature of the stream.)

(C) If heat were transferred at a higher rate than that calculated in part (A), what could you deduce about the state of the product stream?

Explanation / Answer

b. The product stream will be a mixture of vapor and liquid.

c. The product stream will be a supercooled liquid.
