You could pick the ESC that is designed for the maximum continuous power plus some safety margin. The spec sheet claims 52A. I'd go for anything that'll do 60A unless you have a reason to compute lower due to low head loading or similar. This is, of course, if you meet the ESC thermal requirements.
If the ESC meets the current requirements in your desired mode of flying then it will work. Of course, not all ESC or motor datasheets are honest, or even list duty-cycling requirements, and you appear not to have a torque budget on your calculation.
I usually measure to get in the ballpark, select an ESC, validate to the maximum operating limit on a teststand, and hope for the best. Your approach to this may be different.
