Magnetic pumps are often used for the transportation of water between two given systems. They are often used in large scale aquariums, for their reliability, and their low operating cost.
No you can not, Even if you could use a external pump, you would still have to take the pump out of the tank and modify the sending unit so it would pick up the fuel and pump it.
Yes, you would actually prefer to use it when the pump is running
A magnetic needle meter, or a simple compass.
One possible use for a SHURflo water pump is for use on one's RV, or recreational vehicle. Another possible use for a SHURflo water pump is on one's marine craft, or boat. A third possible use for a SHURflo water pump is for use in one's personal space.
Probably not. It's unlikely that a tire pump (particularly if it's a manual one) would give enough air flow for air brushing.
Magnetic paper is fairly new product. It can be used for home decorations or for use in crafts.It comes in matt or glossy.The back of each sheet is magnetic so you can stick your craft to the fridge by sticking one side to what you have made and the other to the fridge.Just use your printer to print out what you like on your magnetic paper and use for whatever purpose you were trying to create.
it is safer.
i believe you would use the same set up as you would for a pump shotgun
To find the direction of the magnetic field, you can use a compass or a magnetic needle. The needle will align itself with the magnetic field lines, pointing towards the direction of the field.
There are still magnetic fields in space - especially if you remain close to Earth. But magnetic compasses are usually designed to use gravity, which you won't have if you are in free fall. A specially-designed magnetic compass would work, though.
In a normal (centrifugal) pump you'd have a motor turning a shaft, then the shaft going through into an enclosed space where the pump wheel/impeller/rotor would sit. It's a simple enough design, but it relies on a good seal where the axle passes from the pump housing to the motor. And creating that seal can be difficult. It needs to be tight enough not to leak while still allow the axle to turn freely. It should last for ages too. Tricky. "Magnetic drive" for pumps refers to that instead of having a drive shaft going through the pump housing to the motor, what connects the pump to the motor is a powerful magnetic field. This field acts straight through the wall of the pump housing. Basically there's one magnet stuck to the pump wheel/impeller/rotor and another to the spinning end of the motor. And just like you can "magically" move a magnetic object on top of a table by moving another magnet underneath the table, the pump wheel will spin with the motor, even though there's no material connection between them. This lets you use a fully enclosed pump housing w/o any axle seals that can wear out and leak. Quite clever.
You can't. The only thing the earth's magnetic field can tell you is the direction from where you are toward the earth's magnetic pole. That doesn't tell you anything about where you are.
