Alright so my car's battery died and I popped the hood only to discover that one of my pipes connected to the engine has ruptured. I want to know what is this part called, what caused the damage and how much to replace or if I can do it my self.
Appears to be your radiator hose, did the car not overheat on you? I'd suspect you lost most of your coolant. A new one is fairly cheap, I hope you didn't drive it around too long like that though.
