Estimate the footprint for a shell-and-tube heat exchanger from the following design data:

• Area = 145 m²
• Hot side temperatures: in at 300°C, out at 195°C
• Cold side temperatures: bfw at 105°C, mps at 184°C
• Use 12 ft, 1-in OD tubes on a 1-1/4-in square pitch, use a single shell-and-tube pass because of change of phase on shell side
• Use a vapor space above boiling liquid = 3 times liquid volume
