Saturated stream at 100 lb/in2 abs is used to heat CO2 in a cross flow heat exchange consisting of 4 1/4 in OD brass tubes in a square in-line array. The distance between the tubes centers is 3/8 in, in both the normal and parallel directions. The CO2 flows across the tube bank while the steam is condensed on the inside of the brass tubes. a flow rate of 1 lb/s of CO2 at 15 lb/in2 abs and 70 degrees F is to be heated to 200 degrees F.

Estimate the length of the tubes to accomplish this heating. Asasume that the steam side haet transfer coefficient is 1000 Btu/h-ft2-F and neglect thermal resistance of the tube wall.
