The time that I've consistently seen is about 20 seconds.

Depends what route it takes and how active the person is at the time. 

but total blood volume is ~5 liters, flow rate in aorta at rest is ~100cm3 per second: 5000/100 = 50 seconds

Indeed. The travel time is affected by route. All blood goes from heart -> lungs -> heart -> body -> heart -> lungs....
Now if the body portion of the route is your foot, it'll take longer to circulate compared to the body portion of the route being your coronary arteries.
