VENTILATION QSB 1714 Prepared by: Mariatul Liza bt Meor Gheda Introduction Definition: The process of changing air in an enclosed space. A proportion of air within the enclosed space should be continuously withdrawn and replaced by fresh air. Drawn in from a clean external source: • At as high an elevation as practical…where more polluted air occurs at the relatively low levels found in congested towns and cities. Why do we need ventilation? Ventilation is needed

Completion Problems (Elasticity) 1. A steel wire of length 4.7m and cross-sectional area 3×10-5m2 stretches by the same amount as a copper wire of length 3.5m and cross-sectional area of 4×10–5m2 under a given load. What is the ratio of the Young’s modulus of steel to that of copper? For Steel l1= 4.7 m‚ a1 = 3.0 x 10-5 m2 Y1= Fl1/a1∆l Y1= (F x 4.7m)/ (3.0 x 10-5 x ∆l) For Copper L2=3.5 m‚ a2 = 4.0 x 10-5 m2 Y2= (F x 3.5m)/ (4.0 x 10-5 x ∆l) Dividing Steel by Copper Y1/ Y2

The Star Wars Trilogy‚ the first being the phantom menace‚ released in 2005 in an attempt to fill in the gaps in terms of the beginning of the epic tale and effects not previously possible in the original trilogy due to lack of technological knowhow was labeled a failure by the majority who filled the cinemas with high expectations. This also showed in the box office as it only netted about 43.5 million dollars when films like Chicago‚ even with all the critics managed to bag about 170.6 million

the soil amended with 100 m3 haÀ1 of untreated OMW. However‚ it slightly decreased to 1.15 in the soil amended with 400 m3 haÀ1 of treated OMW. The treated OMW increased the total mesophylic number while the number of fungi and nitrifiers decreased. Actinomycetes and spore-forming bacteria were neither sensitive to treated nor to untreated OMW. The total coliforms increased with higher doses of treated and untreated OMW. A toxic effect of the untreated OMW appeared from 100 m3 haÀ1. This toxicity was
