ine bad effects of accuracy. 2. Pipeline noise Noise and tremble are not generated by pipe itself but hydraulic shock, pipe resonance and pressure pulse. Here explain, combining operat fuel dispenser ion and maintenance of fuel dispense, these reason for noise and tremble 2.1 Hydraulic collision Hydraulic collision refers to the phenomenon in which oil pressure in pipeline is increased quickly as pipe switch open or close or liquid changing flow direction. Hydraulic collision could lead to pipeline noise, which are result from piston changing direction of measurement transducer and witching on or off pipe valve. Δρ= 12lv11+EoE·dδ (v2=0,t≤T) (2-10) Δρ= 12lv11+EoE·dδ ·Tt (v2=0,t≤T) (2-11) Δρ= 12lv11+EoE·dδ ( partial v2�?,t≤T) (2-12) Δρ= 12lv11+EoE·dδ ·Tt (partial v2�?,t≤T) (2-13) In above formulae: Δρ── increasing pressure value; υ1── previous velocity of flow υ2── latter velocity of flow T ── time that start from collision to reflect T=2la T ── changing time of velocity of flow fromυtoυ2 E0 ── elastic volume of fluid cubage E ── elastic modulus of pipeline d ── inner diameter of pipe δ── pipe thickness l ── diffused distance of shock wave a ── diffused speed of shock wave The above formulae illustrate four kinds of stock pressure on pipe in corresponding operations in which switching on or off nozzle quickly or slowly. They also explain that slowly switch on and off nozzle generating less col fuel dispenser lision pressure than that of rapidly under a certain parameter of pipeline system of fuel dispenser. Similarly, it is applicable to stock noise. Therefore, user shall slowly turn on and off nozzle in operation so as to reduce hydraulic stock and noise, and prolong fuel life service of fuel dispenser. Most of manufacturers of fuel dispensers have mounted anti hydraulic stock device in hydraulic system in order to abate the effects to fuel dispensers. fuel dispenser

partly because investors expect them to be bought dearly by the big banks. One argument commonly used in favour of mergers, in banking as in many other industries, is the pursuit of e fuel dispenser conomies of scale in areas such as procurement, systems, operations, research and marketing. But the gains from that in the mass production of financial services, though not necessarily illusory, can be elusive. There is a sizeable literature of academic papers claiming that economies of scale can be exhausted by the time a bank reaches a relatively modest size. A study of European banks in the 1990s, published by the European Investment Bank, put the figure for savings banks as low as ¬600m ($760m) in assets. More recent studies suggest far higher thresholds, up to $25 billion. Big banks might even dispute that there is a limit at all. But at some point diseconomies of scale will also start creeping in. Management will find it harder and harder to aggregate and summarise everything that is going on in the bank, opening the way to the duplication of expense, the neglect of concealed risks and the failure of internal controls. Something of that last problem afflicted the world s biggest bank holding company, Citigroup, in 2002-05, when it was rocked by a string of compliance problems. America s Federal Reserve reacted by telling Citigroup to suspend large acquisitions, but lifted the order in April this year when it judged that the company had got better controls in place. Another argument commonly made for mer fuel dispenser gers is based on economies of scope, the proposition that related lines of business under the same ownership or management can share resources and create opportunities for one another. The basic economy of scope common to almost all banks is the taking of deposits on one hand and the making of loans on the other. The bank gets to re-use its depositors money profitably. The skills and information useful on one side of the business tend to be useful on the other side too. But does the same hold good w fuel dispenser
