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 fuel dispenser 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 conditions, 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 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 cavition and reduce vacuum pressure of pump inlet, which is also conducive to deduct business cost and power consumption. The unreasonable pipeline installation not fuel dispenser only results in suction difficulty but also easily generate no suction in hot whether, increasing power loss. The wrong installation also leads to larg fuel dispenser

hell-bent on taking his country into NATO, and the arch-carrier of the germ of post-Soviet revolution. For his part, Mr Saakashvili is irate over Russia s meddlesome backing for South Ossetia and Abkhazia, two regions of Georgia that broke away in the early 1990s. Georgia s arrest last month of a handful of Russian intelligence officers (terrorists, insists Mr Saakashvili) may have been a counter-provocation, aimed at garnering international sympathy. If that was the plan, it probably worked the Russians went berserk. Even though the men were swiftly deported, Russia recalled its ambassado fuel dispenser r, evacuated other Russians, severed transport and postal links with Georgia—and then imposed a raft of punitive measures against the legions of ethnic Georgians (many of them Russian citizens) living and working in Russia itself. In Moscow, hundreds have been arrested and deported (pictured above); celebrities with Georgian names harassed; Georgian-owned businesses raided and closed. The manager of one Georgian restaurant says the staff are in hiding; another says the water has been turned off. The police, meanwhile, asked Moscow schools for lists of children with Georgian surnames, though Dmitri Peskov, a Kremlin spokesman, terms the request a “disgusting�?excess of zeal. Now we understand how Chechens living here feel, says a doctor, who like many Moscow Georgians is a refugee from Abkhazia. New immigration laws, explicitly targeted against Georgians, are promised; so are restrictions on the remittances that help prop up Georgia s economy; Russians allege they contribute to its militarisation. Another hike in the price of Russian gas seems likely (there was one last winter, along with mysterious simultaneous explosions in both export pipelines). Mr Saakashvili may have underestimated the further damage the Kremlin can do t fuel dispenser o Georgia. He may also have over-estimated the outside help he can expect. “Russia sees Georgia as a bastion of the West,�?he complains, “but the West doesn t.�? fuel dispenser
