The stroke volume is the volume of blood output with each beat of the heart. This is 110 ml/beat.

Next, we know that the number of beats is 90 per minute. So the volume output is:

90 beats / min * 110 ml/beat

= 9.9 L/min

Next, we may also figure out the hourly output by using:

9.9 L/min * 60 min/hr

594 L/hr
