Please tell me if this is correct calculations or what is wrong.

This is a hypothetical question, about reading a compressor map. If an engine that is 140CID, would theoretically comsume 243 CFM at 6,000prms. That would be about 18.6 lbs/min, with .0765 lbs = 1 CFM. PR of 1.5 would change that number to 27.9 lbs/min, letter 'B'. At 1,000rpms, letter 'A' the air flow at 1.5 PR would be 4.65 lbs/min. If that is all correct does the green line, letter 'C', show where 1.5 PR would start at minimum RPM, about 2,000rpms?
