The aorta in an average adult has a cross-sectional area of 2.0 cm^2. calculate the flow rate of blood of 1.0 g/cm^3 in the aorta if the flow speed is 43 cm/s. answer in units of g/s. (i did this part and the correct answer is 86) assume that the aorta branches to form a large number of capillaries with a combined cross-sectional area of 2.9 × 10^3 cm^2. what is the flow speed in the capillaries? answer in units of cm/s.

As we know that flow rate will always remains the same

so here the flow rate from aorta = flow rate through large capillaries

so here we will have

flow rate through Aorta =

now we can also say that flow rate through capillaries is given by

as we know that

now from above formula

so the speed will be 0.0296 cm/s through capillaries

gets less

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
