Question

The basic function of the carburetor of an automobile is to atomize the gasoline and mix it with air to

promote rapid combustion. As an example, assume that 30 cm3 of gasoline is atomized into N spherical

droplets, each with a radius of 2.0×105 m. What is the total surface area of these N spherical droplets?​

Answer 1

Answer:

4500 cm^2

Explanation:

Volume of N droplets= 4/3* π* R^3 * N

where R= 2*10^-3 cm

which is equals to the volume of gasoline atomised that is 30 cm^3

equating these two and solving for N

we get N= 895246554.9

Now,

total surface area of N droplets = 4πR^2 * N

which is 4500 cm^2
