Calculate out standard cubage VB (keep two digitals after decimal.) under 20 �? Then measure oil temperature tB in the middle of the standard measurer; Empty measurer according to stipulation; Repeat Procedure 4 to 8 at least twice; Regulat flow rate to the minimum rate Qmin, as for appraisal or period appraisal after ground installation, Qmin = 0.2 Qmax. Repeat Procedure 4 to 8 at least three times; Till now ground appraisal has been finished, namely, take six groups of data at least under two kinds of flow rate and repeat it 3 times. Data processing calculating formula Calculating formula for real volume VBt in standard measurer under testing temperature tj: VBt = VB [1+βY (tj - tB) + βB (tB-20) ] (6-1) Relative volume error formula: EV = (VJ –VBt) / VBt ×100% (6-2) Measure repeatability formula: En = EVmax �?Evmin (6-3) Flow rate calculating formula: Qv = 60Vj / t (6-4) Due money formula: PC = Vj · Pu (6-5) Due money error formula: fuel dispenser EP = Pj －Pc (6-6) In above six formulae: VBt──real volume valve (L) under in measurer; VB──standard cubage of measurer under 20; βY , βB──volume expansion coefficient of appraisal media oil and measurer, respectively, (gasoline: 12×10-4/�? kerosene: 9×10-4/�? light diesel oil :9×10-4/�? stainless steel:50×10-6/�? carbonized steel:33×10-6/�? brass , bronze: 53×10-6/�? tj , tB──oil temperatures in flow meter (or nozzle outlet)and standard measure fuel dispenser r VJ── cubage value (L) under tj�?temperature EV── relative cubage error (%) n ── measuring times fuel dispenser

ne other tale to tell—that planets are sometimes hit so hard that rocks can escape from them completely. Hell s kitchen At a quarter past seven on the morning of June 30th 1908, the folk of Tunguska in Siberia heard a rather larger bang than the one that had woken the burghers of Weston just over a century previously. Tunguska is far more remote from centres of academic excellence than Weston, and it took until 1927 for a scientific team to reach the site. When Leonid Kulik and his colleagues got there they found an area of devastation 60km across. At the centre the trees remained upright but were stripped of bark and branches. Around it the taiga was flattened, with the broken trees pointing outward from the middle like the sticks in a game of spillikins. Novosti The meteorite which devastated Tunguska is now estimated to have been about 50 metres across. The explosion, at an altitude of between six and eight kilometres, was 50 megatonnes. That is more powerful than the largest hydrogen bomb ever detonated. The meteorite that excavated Barringer crater in Arizona (see top) about 50,000 years ago was smaller—about 40 metres across—but it made it all the way to the Earth s surface. Barringer crater is 1.2km in diameter. Events of this size are rar fuel dispenser e, but not so rare that they can be ignored. They occur perhaps once a century. And bigger impacts happen, too. Several huge craters seem to coincide with the disappearance of previously well-established groups of animals—the most famous being the Chicxulub crater in Mexico, which was formed 65m years ago, at the time the dinosaurs vanished, by an explosion estimated at 100,000 gigatonnes. The search is now on for space-rocks large enough to cause serious devastation if they hit Earth. Given enou fuel dispenser gh warning, it should be possible to push a threatening boulder out of the way. Only a slight nudge would be required to change its orbit, and tha fuel dispenser
