Question about cumulus clouds

  1. Sep 6, 2007 #1
    1. The problem statement, all variables and given/known data
    A cubic centimeter in a typical cumulus cloud contains 50 to 500 water drops, which have a typical radius of 10 µm. For that range, give the lower value and the higher value, respectively, for the following.
    (a) How many cubic meters of water are in a cylindrical cumulus cloud of height 2.7 km and radius 1.0 km?
    give the lower and upper limit

    2. Relevant equations



    3. The attempt at a solution

    i have converted the units to m cube because thats what the answer wants but i just don't know how to continue

    You need to work out the volume of a sphere 10um in diameter - this and the 50-500 gives you the volume of water in 1 cc
    Then you need to know how many cubic cm there are in a cubic metre.

    The volume of the cloud is the area of circle of radius 1.0km times the height 2.7km, work this out in cubic metres.

    so do i multiply the volume of the sphere with 50 and 500 separately

    Yes you would because it says to give the upper and lower limit.
