Complete combustion products exit at 1200 K, 3 atm. Water enters the boiler tubes as saturated liquid at 100C and leaves as saturated vapor. Assume no dissociation. WebIsopentane, also called methylbutane or 2-methylbutane, is a branched-chain saturated hydrocarbon (an alkane) with five carbon atoms, with formula C 5H 12 or CH (CH 3) 2(C 2H 5) . Isopentane is an volatile and flammable liquid.
