For increasing the pressure in the bottle, as gravity works more and fluid comes down with more force........if the bottle is kept below the arm level, the pressure in the vessels which is greater than the pressure in the bottle becuase of pumping of heart would lead the blood to enter in the bottle and thus the process would reverse..this is why it is kept above arm level !

Just to increase static energy of the fluid, more then that of the blood in the blood vessel. This way fluid passes from bottle to patient's blood vessel, not the vice versa.

Because of gravity to help the fluid go into the patient

The pressure in the bottle has to be greater than at the level of the right atrium.

So that the fluids that are going in, cannot flow back through the drip which would cause more harm than good.
