In an air separation plant, air is cooled and its components are separated from the mixture. cooled oxygen at a temperature of 20°c must be heated to a temperature of 30°c for accurate metering. the oxygen flow rate at 30°c is 0.01 kg/s. air (available at 35°c and 0.015 kg/s) is used as the heating medium. a number of 3 x 2 schedule 40 double pipe heat exchangers that are 2 m long and made of galvanized steel are available. determine how many are required. calculate outlet temperatures and pressure drops. compose a summary of performance chart.
