Will the transaction be made ?

Almost certainly.

More slowly ?

Probably

Is it possible to add fee to a already sent transaction ?

Not easily.

You might try looking into Peter Todd's replace-by-fee-tools, specifically bump-fee.py for an alternative.

Unfortunately it's quite urgent Sad

Then send a second payment (with a fee), and request a refund for the first payment.

If you want to make sure that Bitcoin Core always includes a fee, change the default fee in "Preferences" to 0.0001 BTC.

But if fee rate is different from Preferred rate how do this will be treated. ??
