EQUATIONS OF MOTION
Based on Newtons second law.
Fx = m ax
In the fluid flow, following forces are present:
1. Fg, gravity force.
2. Fp, the pressure force.
3. Fv, force due to viscosity.
4. Ft, force due to turbulence.
5. Fc, force due to compressibility

Chemical Hazards
Over 10,000 children in 46 countries were born with
deformities such as phocomelia.
The drug Thalidomide (Distaval) was licenced in
Britain as an antiemetic in 1958 & withdrawn in late
1961.
Between 1959 and 1962 approx. 2,000 babies were
A/c to WHO, 2.4 million people worldwide
die each year.
Average of 274 deaths every hour
from the effects of air pollution.
Most of these deaths occur in Asia, with
about 7,50,000 deaths per year in China alone
(5,00,000 from indoor air pollution).
