Ethanol isvaporized at 78 oc (hfg= 846 kj/kg) in a double-pipe parallel-flow heat exchanger at a rate of 0.04 kg/s by hot oil (cp= 2200 j/kg. k) that enters at 115 oc. if the heat transfer surface area and the overall heat transfer coefficients are 6.2 m2and 210 w/m2.k, respectively, determine the outlet temperature and the mass flow rate of the oil using (a) the lmtd method and (b) the effectiveness method.

i mean i gues

explanation:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.
