South African Politics!?!?
FEEL IT? was the cry of the month for June/July. Now the footy is gone, and what do we have? a mother of all babalaases to carry thru till some league somewhere starts. While waiting for the J-League or the PSL to commence, there's still the issue of SA politics to deal with. Foreigners are being blamed for taking local folks jobs, women, social grants, cars, houses, etc. To think of it, the people blaming me for taking their jobs do not realize that as a Professional Engineer, I've got the licence to practice anywhere i fancy, and did i take anyones freaking job? FUCKING HELL NO!! So this thing has to be looked into properly, critically and with clear minds. In one of them Times blogs I've realized that people think that if you're foreign you're directly competing. I'd rather think of it as directly complementing. For example, I came with my skills from wherever i acquired them, somebody pumped the money, one brought the muscle, one trucked in the materials and as a team working together Soccer City, Gautrain, etc were built. Everyone is happy, job competition? hell no!
Then 12th of July everything almost collapsed into such a load of thrash that you never really thought people will do. Somehow somewhere somebody has been planning some xenophobia attacks, or was it planned this?
(p.s. the X in xenophobia is a very deep Z like slur, as in er.....like........... Xavi, ah that simplifies it).
So who do we blame? Can't blame the government, we voted for them init? Yip we did. The foreigners for taking the jobs? well i dunno.
There's gotta be an understanding of the exodus of people dynamics. Until then, we can blame whoever we hate. Moses lead the Israelites out of Egypt in fear of persecution by Herod and his cronies back then. They went and landed into the "Land of milk and honey". And what is it now? the most volatile and violent region in the history of mankind in recent times. Why all this fighting? It's because some warped mind thinks they're superior from another. South Africa? It's more or less the same. It's the same bullshit happening in the Middle east that's about to blow up in this land. Watch this space.
In the days of the struggle, our very own political leaders and icons had to skip country so they can garner support and hide from the then rule. And where were they? Mozambique, Zimbabwe, Malawi, etc..... and hence when the land is back into the hands of the "rightful" owners our brothers want a slice of bread and instead they're the ones being sliced with machetes!! And I really can't blame the political leaders for that. It's people who don't even try to read the History of South African politics that are to blame. If and only if they had good education to read that is.
We need to start somewhere (school maybe so we can read). And let's show some love. Yeah, where's the love?
Arividerchi!!

Hydraulic design of pump sumps and intakes
Chapter 1 of ?
The Design of a pumping station involves many aspects of civil and mechanical engineering, the hydraulic design forming only part of the whole process. The hydraulic design deals with the channelling of liquids into the pump, the flow through the pump, and the discharge system.
An unsatisfactory hydraulic design of intakes and sumps could have far reaching implications on the overall performance of the pumping station. The design of pump intakes and sumps is amenable to solution by hydraulic model analysis. However, without proper appreciation of the design criteria, an indifferent first design and layout often results, requiring extensive alterations to the model and considerable difficulty in achieving a satisfactory design.
This document deals only with the flow and control of water from it’s entry into the pumping station up to it’s entry into the pump.
The fluids under consideration are water and air, the water being pumped and the air being above the free surface or, in some cases, being entrained as bubbles within the water. However, the results will apply in principle to other fluids used in the process industries as long as allowance is made for effects arising from the difference in the fluid properties. Viscosity and specific gravity are the most important properties considered.
