pump blood
The heart of a resting adult pumps blood at a rate of 5.00 3 L/min. a Convert this to cm /s . b What is this rate in m 3 /s ? 3. Blood is pumped from the heart at a rate of 5.0 L/min into the aorta of radius 1.0 cm . Determine the speed of blood through the aorta. Blood is flowing through an artery of radius 2 mm at a rate of 40 cm/s. Determine the flow rate and the volume that passes through the artery in a period of 30 s. The Huka Falls on the Waikato River is one of New Zealands most visited natural tourist attractions see Figure 12.29 . On average the river has a flow rate of about 300,000 L/s. At the gorge, the river narrows to 20 m wide and averages 20 m deep. a What is the average speed of the river in the gorge? b What is the average speed of the water in the river downstream of the falls when it widens to 60 m and its depth increases to an average of 40 m?.
