One cubic centimeter of a typical cumulus cloud contains 110 water drops, which have a typical radius of 10 μm. (a) How many cubic meters of water are in a cylindrical cumulus cloud of height 3.1 km and radius 1.1 km? (b) How many 1-liter pop bottles would that water fill? (c) Water has a density of 1000 kg/m3. How much mass does the water in the cloud have?
"\\text{let }V_{cm^3}\\text{ volume of water in }1cm^3"
"V_{cm^3}=V_{drop}n"
"n= 110"
"\\text{we assume that a drop is a sphere}"
"V_{drop}=\\frac{4}{3}\\pi{R^3}"
"R =10 \u03bcm= 10*10^{-6}m= 10^{-5}m=10^{-3}cm"
"V_{drop}=\\frac{4}{3}\\pi{10^{-9}}cm^3"
"V_{cm^3}=\\frac{440}{3}\\pi{10^{-9}}cm^3"
"k = \\frac{V_{cm^3}}{1cm^3}=\\frac{440}{3}\\pi{10^{-9}}\\approx4.6*10^{-7}"
"k -\\text{coefficient when multiplied by which total volume}"
"\\text{we get the volume of water}"
"a)V_{cloud}=\\pi{R^2}h"
"R=1.1km=1100m;h=3.1km=3100m"
"V_{cloud}=\\pi*{1100^2}*3100\\approx1.18*10^{10}m^3"
"V{water}=k*V{cloud}"
"V{water}=4.6*10^{-7}*1.18*10^{10}=5.43*10^3m^3=5430m^3"
"b) 1 -liter = 1dm^3=10^{-3}m^3"
"\\text{count bottles}=\\frac{V{watter}}{10^{-3}}=\\frac{5.43*10^3}{10^{-3}}=5.43*10^6=5430000"
"c) m =\\rho*V"
"m = 5430*1000=5430000kg"
Answer:a)5430 m^3 b)5430000 c)5430000 kg
