Calculation behind the attached table values for tank sizing

Calculation behind the attached table values for tank sizing

Calculation behind the attached table values for tank sizing

(OP)
"How big a tank?
Problem: An absorption machine condenses 12,000 lb. of steam/hr. Assuming the flash tank is vented to the atmosphere, determine the size of the flash tank required with a steam pressure of 12 PSIG.
Solution: Enter table 1 (attached) at 12 PSIG steam pressure, moving horizontally to 0 PSIG. Find .75, which is the number of square feet required for each 1,000 lb. of condensate. Since 12,000 lb. of steam are generated, it may be determined that by multiplying 12 x .75, 9 sq. ft. of sur- face will be required, or that the diameter of the tank in feet times its length in feet must equal 9. Thus, a tank 2 ft. by 4.5 ft. may be used."

The above problem and solution including the attached table are taken from google search. My question is how to get the values in the table. I surrendered after a full three days of frustration. Thanks in advance.

RE: Calculation behind the attached table values for tank sizing

Was the table provided by the flash tank manufacturer's site?

The table was created using the Figure 5 of Ahlgren 1991 ASHRAE August.
