Ammonia is used in liquid form for a process and is needed at a temperature of 15°c. it is available at 0°c. liquid carbon dioxide is used rather than water as a heat source (using water may lead to trouble). liquid carbon dioxide is available at 5°c and a mass flow rate of 1.25 kg/s. a 15-m-long double pipe heat exchanger, made of 21/2 x 11/4 type k copper tubing, is available for this service. for an ammonia flow rate of 1.2 kg/s, calculate outlet temperatures and pressure drops. will this setup work?
