Question

What is the work generated by a healthy adult who circulates 9 l of blood through the brachial artery in 10 min 2 kj?

Answer 1

You have also the total power generated is 200W

To figure out the kind of exercises, you need to master the definition of each unit. for example
power: watt (W) is joule/sec
Work: is Newton. meter = Joule

To obtain the work done by the adult, we have to convert the power (watt) into a work by multiplying by the time (
`(Joule)/(seconds)` * seconds = Joule)
10 minutes is 60 * 10 = 600 seconds

200Watt * 600 second = 120000 joules = 120 Kj

So the work is 120Kj
