A house has a volume of `600 m^(3)`.
What is the total mass of air inside the house at `0^(@)C`?

A house has a volume of 600 m^(3) . If the temperature rises to 25^(@)C , what mass of air enters or leaves the house?

A wind with speed 40 m//s blows parallel to the roof of a house. The area of the roof is 250 m^(2) . Assuming that the pressure inside the house is atmospheric pressure, the force exerted by the wind on the roof and the direction of the force will be : (rho_(air)=1.2 kg//m^(3))

A wind with speed 40m//s blows parallel to the roof of a house. The area of the roof is 250 m^(2) . Assuming that the pressure inside the house is atmospheric pressure, the force exerted by the wind on the roof and the direction of the force will be (P_(air) = 1.2 kg//m^(3))

Atmospheric air has 78 % N_(2) , 21 % O_(2) , 0.9 % Ar and 0.1 % CO_(2) by volume. What is the molecular mass of air in the atmosphere ?

Air flows horizontally with a speed v = 108 km/hr . A house has a plane roof of area A = 20 m^(2) . Find the magnitude of aerodynamic lift on the roof . [ Density of air = 1.3 kg//m^(3) ]

Air of density 1.3 kg//m^(3) flow horizontally with a speed 106 km//h . A house has a plane roof of area 40 m^(2) . Find the magnitude of aerodynamic lift on the roof.
