I have a mountain bike and recently the rear wheel has gone flat and every time i pump air into it up to 50 psi it deflates after a few minutes I also hear air coming out a certain part of the wheel but i'm not sure what to do since this is my first time that I have gotten a flat wheel

Edit: I took apart the wheel and found a tiny hole in the tube, should i replace the tube or patch it?
