Problem 4 Water is flowing in a pipe with varying cross-sectional area. At the point A, where the cross
sectional area of the pipe is 0.0700 m2
, the velocity of the water is 3.50 m/s. Compute:
a) The speed of the water at point B, where the cross-sectional area of the pipe is 0.105
m2
;
b) The speed of the water at point C, where the cross-sectional area of the pipe is 0.0470
m2
;
c) The rate at which water flows in the pipe (in m3/s);
d) If point B is 10.0 m below point C, what is the difference in pressure between point B
and point C?

Exploitation, invasive species

If the government introduces laws prohibiting hunting, it would somewhat reduce the impact of exploitation would have on the biodiversity because hunting is mainly done for the purpose of fun or to derive valuables from animals like skin, horn, ivory, venome for selling them in the international market and making huge profit from them. Introduction of prohibition law on hunting will reduce killing and exploitation of animals for their valuables.

If laws prohibiting introduction of new plant or animal species within the country are passed, it will curb the effect of invasive species would have on the seas. Invasive species are those living species which are arrive or immegrate to new locations in search of resources. These species compete with native species which results in decline of native species. This will result in disturbance in actual sea biodiversity as this will result in decline in native sea species and may also lead to extinction of native species.
