In Aspen Hysys, a heat exchanger block has been added onto the flowsheet and inlet/outlet streams have been connected. Both the hot side and cold side inlet streams have been fully solved. Meanwhile, we have provided the pressure drop on shell side and tube side of the exchanger. What else do we need specify to solve the heat exchanger block? (1) The duty of the exchanger (2) The outlet temperature of shell side stream a. Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient. b. Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient. c. BOTH Statement TOGETHER are sufficient, but NEITHER Statement ALONE is sufficient d. EACH Statement ALONE is sufficient e. Statement (1) and (2) TOGETHER are NOT sufficient
