Snow storms can be detrimental to homes because of the weight of the snow can be heavy enough to overload the roof which are designed to withstand a pressure of 20 lb/in2. You are concerned about a meteorologist’s prediction for 24 inches of snow, and scratch a quick calculation for your parent’s 60 °ø 100ft2 roof, using the density of wind packed snow as 400 kg/m3. What is the total weight of the rooftop snow in tons? Does this situation produce a snow load that exceeds design limits?

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
