13 outs twice is roughly 13x4 (using the rule of 2 and 4) or 52% is like 1.1:1 , 50% is 1:1.

You're getting 50:20 -> 5:2 - > 2.5:1 so you need 1/(1+2.5) -> .29 -> 29%

Obviously if you find yourself in this situation you're calling. Only an idiot would fold this at any level, since even against a worst case set and another flush draw face up we have the required odds to call.
