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. fuel dispenser 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 increas fuel dispenser ed 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 only results in suction difficulty fuel dispenser but also easily generate no suction in hot whether, increasing power loss. The wrong installation also leads to larg

stment firms find them useful, either as an indicator of credit quality or as a benchmark to bet against. In the teeming market for opinions, they hardly have a duopoly. The signature failure cited by the big agencies critics is that neither predicted the financial wreckage of Enron and WorldCom. Both maintained investment-grade ratings until the demise of the companies was plain. That said, the agencies relied on financial statements that were later found to be fraudulent—which reflects at least as badly on the SEC s ability to police its own filings as on the analytical ability of the agencies. And in the myriad investigations that followed the collapses of Enron and WorldCom, neither Moody s nor S&P was found to have acted wrongly. Some financial institutions already under the supervision of the SEC may fuel dispenser wish they could say as much. As it happens, there is good reason to change the rules covering rating agencies, by stripping away the protection granted to the biggest of them by the SEC in 1975—the history of which is a good example of the unintended consequences of regulation. At the time, the SEC granted a broker s request to use the bond ratings of Nationally Recognised Statistical Rating Organisations (NRSROs) in determining how much capital it required. The idea of using ratings from leading agencies for regulatory purposes was then applied to a number of other tasks, such as determining which secur fuel dispenser ities could be included in money-market funds and the investment portfolios of insurance companies and state pension funds. That gave the ratings of the NRSROs added value. At first, just three were recognised Moody s, S&P and Fitch. Others were added later, but then merged with Fitch. Many more tried to gain recognition, but only two succeeded Dominion Bond Rating Service in 2003 and A.M. Best in 2005. Remarkably, in the three decades since t fuel dispenser he NRSRO tag was first used, the SEC has never defined what is required to get it, thus creating a clear barrier to entering the rating bus
