The 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))

High speed wind blows over a house. The force on the roof is

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.

The rain water from a roof af dimensions 22 m xx 20 m drains into a cylindrical vessel having diameter of bases 2 m and height 3.5 m. If the rain water collected form the roof just fill the cylindrica vessl, them find the rainfull (in cm).

The rain water from a roof af dimensions 22 m xx 20 m drains into a cylindrical vessel having diameter of bases 2 m and height 3.5 m. If the rain water collected form the roof just fill the cylindrica vessl, them find the rainfull (in cm).

The rain water from a roof of 22\ mxx20\ m drains into a cylindrical vessel having diameter of base 2 m and height 3.5 m. If the vessel is just full, find the rain fall in cm.

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

ABCDE is the end view of a factory shed which is 50m long. The roofing of the shed consists of asbestos sheets as shown in the figure. The two ends of the shed are completely closed by brick walls. If the cost of asbestos sheet roofing is Rs 25 per m^(2) (sq. metre), find the cost of roofing.

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.

An atchitect is working on a design for a solar power plant. While double-checking the blueprint, he realizes that he has made an error: The solar panels will not fit on the roof unless the dimensions of the roof are increased by 0.5%. Which of the following expresses this change in the dimensions of the roof as a fraction of the original dimensions?
