Estimate the number of water droplets, each of radius 0.05 mm, in a cloud that will provide 5 mm of rainfall for metropolitan (urban) halifax.

number of raindrops = 2.23 ×

Explanation:

given data

radius = 0.05 mm

rainfall = 5 mm

to find out

number of water droplets

solution

we know here Area of metropolitan (urban )Halifax

approx =  234.72 km²

= 234.72 × mm²

and

Total volume of rainfall  will be here

Total volume of rainfall = 5 × 234.72 ×

Total volume of rainfall = 1.17 × mm³

and

Volume of each raindrop  will be

Volume of each raindrop  =

Volume of each raindrop  =

Volume of each raindrop  = 5.23 × mm³

so

number of raindrops for this volume of water is

number of raindrops =

number of raindrops = 2.23 ×
