Question

20 m/s Wind is blowing over the roof of a house is the roof has an area of 115m2 what is the magnitude of the force( in a newton) on the roof ?

Answer 1

Answer #1

Applying Bernoullis theorem, 1.2 kg/m3 Density ofair is constant. And let it be, ρ P: Pressure inside the house. P: Pressure

Hence the magnitude of the force on the roofis, F= (240 N/m2)(115 m2) F = 27600 N This is the magnitude of the force on the r

Wind flows over a tilted roof (45o angle), causing an increase in the pressure on the roof to Po P+ AP. The pressure inside the attic/house is sl Pam. The pressure forces are quite high, so that the viscous part of the total stress tensor (equation 6, chapter 6) is negligible in comparison 1. Write the matrix expressing the total stress tensor for the indoor and outdoor faces of the roof 2. Write the force vectors applied to the indoor...
