It is required to air condition a factory building (27m x 18m x 4m). The 27m wall is type B and faces south. The following date is available: Two glass windows in south wall 3m x 1.5m each with internal shade, Lighting load is 20 Watt fluorescent per m2 floor area ; The inside air conditions are, DBT=24 oC and RH=50%. The outside air conditions are, DBT= 40 oC, WBT=30 oC. Other related data are: daily Range (DR)=18.0 oC, Uwall =1.4 W/m2 k, Uglass=3.5 W/m2 k, Scglass =0.7, occupancy = 8 persons doing light bench work and, CLFoccupancy= 0.75. The building is of heavy construction with light color located at 32 N. Calculate the building cooling load from the south wall, windows, lighting and occupancy on August at 4.0 p.m.

An office space contains one (6`x 3`) well- fitted door made of nominal 2" wood. The heat loss through door by infiltration is (3381 Btuh) if Tb.l.=80 F , To= -10 F , and Vwind=15 mph ? True or false
A security camera is to be mounted on a building in an alley and will be subject to wind loads producingan applied force of F0 cos(wf t) where F0 is measured to be 15 N. It is desired to design a mount such thatthe camera will experience a maximum deflection of 0.01 m when it vibrates under this load. The windfrequency is known to be 10 Hz and the camera mass is 3 kg. The mounting bracket is made of a solidpiece of aluminum, 0.02 x 0.02 m in cross section. Determine the length of the mounting bracket (l) that willkeep the vibration amplitude less than the desired 0.01 m. You may ignore torsional vibration and assumethe initial conditions are both zero. Note that the length must be at least 0.5 m in order to have a clear view.
