Question

Suppose that a typical adult heart pumps 5.0 liters of blood per minute. Express this rate in SI units you provided above. M/s. 1cm^3=1mL​

Answer 1

The answer is below

Explanation:

International system of unit (SI unit) are standard units which are universally accepted. There are 7 basic SI units which are meter (m), second (s), kilogram (kg), mole (mol), ampere (A), candela (cd) and kelvin (K).

The SI unit of flow rate is the m³/s.

The conversions needed are:

1 minute = 60 seconds,

1 cm³ = 1 ml = 0.001 ml,

1000000 cm³ = 1 m³,

1 L = 0.001 m³

We have to convert 5.0 liters of blood per minute. to m³/s. Therefore:

`5\ L/minute=(5\ L*0.001\ m^3)/(1\ min*60\ s)=8.33*10^(-5) \ m^3/s`
