How does the petrol pump know when your tank is full?

There's a sensor hole at the end of the nozzle that shuts it off at the first hint of backwash

it is supposed to when the bufers get full

You need to use Boyle's Law to calculate this.  Pressure is directly related to volume.  PV(inside) = PV(outside)  If the pressure of your tank is 2500PSI and holds 50L and atmospheric pressure is 14.7PSI we can calculate the volume once all the gas is released.  Since we can not get the last 14.7PSI out of the tank due to atmospheric pressure we have to subtract that from our tank pressure.  So we have...\n(2485.3PSI)(50L) = (14.7PSI)(X)  solving for X we would have a total volume of 169.07L.  Divide this by the flow rate and you can determine how long it should last.

The amount of gas is determined by the size of the tank.  At most tracks, it is 22 gallons, and 2 tracks, it is 13 gallons.  Horsepower has nothing to do with the amount of gas each car holds.  If you are asking about fuel mileage, that is a completely different answer and is determined by the individual cars and how each driver drives their car.

It can set the gasoline on fire. Eventually there could be an explosion. I've seen films of people being lit on fire while pumping gas. \nHere's a link that verifies fire can happen.\n.

A coolant recovery tank on a car is a tank that handles overflow from your radiator.  The volume of the coolant in your car changes with the temperature of the engine.  WHen the engine is hot, the coolant expands.  If it expands enough, it no longer fits in the coolant system.  It will then overflow into the coolant recovery tank.  WHen the engine cools again, that coolant is then pulled back into the radiator.

They will both drain at the same rate and the tanks will empty at the same time. The tank with the shortest drain will appear to have emptied first because it's drain pipe is shorter. The liquid has further to travel in the long drain and will finish after the short drain, but theoretically, the tanks will empty at the same time, the liquid in the long drain will just be in situ longer.

Usually a small tube inside the delivery nozzle, which normally is not submerged. When it becomes submerged, that triggers the valve to shut off. This is explained in detail in the ref. \nIn some home oil tanks there is a whistle driven by an air pipe from the tank. The bottom of the pipe is a few inches (25 gallons' worth) below the top of the tank. The incoming oil displaces the air which blows the whistle. When the bottom of the pipe gets covered by the oil the whistle stops and the oil man wakes up, one hopes.

id go to the manufacturer if it didn't come with a manual\n\nor just open the cover and put grease on everything that moves\n\nor call your local tide & time & weights & measures service  agency  place.  if they verify that what the pump says is being pumped actually is, then they might also know maintenance or atleast where to find it.

If you're doing this to save on fuel economy, you're kind of missing the point.  Your engine needs the same stoichiometric amount of fuel to run, no matter the dilution level.  In other words, your engine will burn the same number of gasoline molecules, whether or not there is water present.

there are three different thing,s that will set the alarm off,,,first is oil mixture sensor,second is rev-limiter,help,s control of over racing the engine,and third is the temperature,of the engine,any one of these means you should check the engine,my boat has one,and the last time it went off the water pump was going out,and the motor was running,,just a little hotter than it should have,,but lucky for me i checked it,,and it helped save my motor,,and really that,s the job it was designed to do,,so you might want to take a little time and look your engine over,it may help save your engine too.

think of you engine as a vacuum. when you depress the gas pedal it opens the air intake, allowing more air and fuel to enter the engine, creating a bigger explosion inside of the engine which then causes the engine to spin faster, thus it speeds up.

in most modern vehicle a trip meter is given on the dashboard meter. the dashboard meter normally shows the current kilometer reading. there is a small black coloured knob comming out of the dash board meter. if you press it once it will show     trip A and reading 0.0   to calculate average of the vehicle you have to fill the fuel tank to full capacity and make the trip meter reading 0.0 then you go for a long drive and comeback and fill the fuel tank again full and note down the amount of fuel filled. finnally divide the trip km with the amount of fuel that was filled/used up to get the average.\n\nin some old cars if no trip meter is there and you have a carburettor vehicle then do the following procedure. fill a bottle with 1 litre petrol.take a small rubber pipe of length approx 2 to 2.5 mts. put one end of pipe in the petrol bottle.remove the carborator inlet pipe and put the other end of rubber pipe to the carburettor inlet. also remove the fuel return pipe and fix another rubber pipe of 2.5 mts length to fuel return and put other end in fuel bottle. you can sit holding the petrol bottle in the front seat of the car while somebody drives the car. drive until the whole 1 litre fuel gets used up. note down the initial and final reading of km.\nnote: the pipes can go upto the carburettor via holes under the dashboard.\nalso fuel inlet will suck the petrol out of the bottle and fuel return will send back unused fuel to the bottle. \nyou better have a experienced mechanic to assist you when you do this.\nhope this helped you out

get a second opinion- Sorry a fuse is good or bad - no middle. you have an issue withe the sending unit in the tank - it is a simple but not a cheap part- most of the sending units have an arm that rides up and down with the fuel level- sometimes where the arm rubs against can loose contact and cause a gauge to read empty- or loose ground withe the tank. should be cheaper than 500.00 maybe

Well you have two tanks on a plane and you use either one. I believe it works just like the ones we have on cars and trucks. With a Float system.\nOh and the gages will change if you stay at an angle lmao. or upside down they register this all lol. I believe they are slow responce gages meaning they do not react real fast to a change in plane level up or down or angle.

The water in the tank is cold. This is condensation dripping down on the burner formed when hot air touches the cold tank. \n\nOnce the water is heated it never gets cold again so you should not hear it again.\n\nGet an "A"
