Narrative:

On departure from ord runway 22L; (ORD5 departure); crew were given 180 heading and complied with this direction after takeoff. Shortly thereafter determined we would not achieve published climb gradient and pm (pilot monitoring) immediately notified ATC. ATC then informed crew of possible conflict; but did not assign different heading or altitude.turning south off runway 22L shortens the distance available to achieve climb gradients on this radar SID with a problematic lack of information (specifically track distance) to determine climb performance. Additionally; with the heading being assigned as the aircraft is cleared for takeoff this provides little time to assess performance. There appears to be a lack of pre-charted information with wat (weight; altitude; temperature) inputs to assist in rapid climb assessment.publish a wat (weight; altitude; temperature) based chart for aircraft based on a worst case track distance off selected runways at ord for specific runways...basically a regulated takeoff graph (rtog). Suggest ord implement more RNAV sids...track distance on established procedures is key. Crews may want to consider requesting headings other than 180 on the ORD5 as well; or request other departure runways with more frequency.
