Rain on the Roof

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))

Water stored in the tank on the top of a roof has:

The water stored in a tank on the top of a roof has:

The sun delivers about 1.4kW m^(-2) of electromagnetic flux to the earth's surface. Calculate A. the total power incident on a roof of dimensions 8mxx20 m. B. the solar energy in joules incident on the roof in 1h. C.the radiation pressure and force assuming the roof to be a perfect absorber.

The rain water that falls on a roof of area 6160\ m^2 is collected in a cylindrical tank of diameter 14m and height 10m and thus the tank is completely filled. Find the height of rain water on the roof.
