ank and fuel dispenser. It is incomprehensive to think that the higher vacuum pressure in inlet the better performance. Here is vacuum pressure of pump inlet formula: PZ = Pa－P1= P gh＋P [(υ1)2/2 ] = P ghf (2-9) PZ ── vacuum pressure of pump inlet Pa── absolute atmospheric pressure P1── absolute pressure of pump inlet g── acceleration of gravity h── height from pump inlet to oil level in tank υ1── velocity of pump inlet hf── energy loss in pipe from tank to pump inlet from formula 2-9, there are three exterior conditions depend vacuum pressure of pump: pressure needed to lift oil, σgh; the pressure that used to increase flow velocity, P [(υ1)2/2 ]; the pressure loss in pipeline, P ghf . Once oil contains air, along with pressure decrease, more air is separated. So dose that along with inlet vacuum pressure increases. Under there condi fuel dispenser tions, cavitation would occur in pipeline, causing pump’s normal operation. In order to prevent above disadvantage effects, pay much attentions to installation of pipeline: ①tank should not be burred too deeply, the vertical distance from bottom valve to fuel dispenser no more than 4m, for example, regulated by some manufacturers with the purpose to prevent higher vacuum pressure of pump inlet; �?the diameter of pipe should not too small. As flow velocity correlate to section of pipeline, vacuum fuel dispenser pressure at inlet of pump will be increased when high velocity in smaller diameter pipe; adopt as few as elbow in pipeline, preventing the connection with different diameter pipe, adopt pipe with smooth pipe wall. Rational installation of pipeline between tank and fuel dispenser benefit avoiding cavitio fuel dispenser n and reduce vacuum pressure of pump inlet, which is also conducive to deduct business cost and power consumption. The unreasonable pipeline installation not only results in suction difficulty but also easily generate no suction in hot whether, increasing power loss. The wrong installation also leads to larg

ness to being yet another intractable problem of the poor world about which little or nothing can be done. For now, though, the money is flowing. About $8.9 billion is expected to be available this year. And, regardless of Dr De Cock s long-term worries, that sum should rise over the next few years. Not surprisingly, a lot of people are eager to spend it. Many of those people—some 24,000 of them—have been meeting in Toronto at the 16th International AIDS Conference. An AIDS conference is unlike any other scientific meeting. In part, it is a jamboree in which people try to out-do each other in displays of cultural inclusiveness the music of six continents resonates around the convention centre. In part, it is a lightning conductor that allows AIDS activists to make their discontent known to the world in a series of semi-official protests. It is also what other scientific meetin fuel dispenser gs are, a forum for the presentation of papers with titles such as “Differing lymphocyte cytokine responses in HIV and Leishmania co-infection�? But mostly, it is a giant council of war. And at this one, the generals are trying to impose a complete change of military strategy. What goes around, comes around When AIDS was discovered, there was no treatment. Existing anti-viral drugs were tried but at best they delayed the inevitable, and at worst they failed completely. Prevention, the fuel dispenser n, was not merely better than cure, it was the only thing to talk about. Condoms were distributed. Posters were posted exhorting the advantages of safe sex. Television adverts were run that showed the consequences of carelessness. Ten years ago, though, a new class of drugs known as protease inhibito fuel dispenser rs was developed. In combination with some of the older drugs, they produced what is now known as highly active anti-retroviral therapy or HAART. In most cases, HAART can prolong life indefinitely. That completely changed the picture. Once the AIDS activists had treated themselves, they began to lobby for the poor world t
