Gasoline flowing through the pipes of a heat exchanger is cooled from $93\backslash$deg C to $37\backslash$deg C by pentane boiling outside the pipes at $35\backslash$deg C$.$ Assuming that all resistance to heat transfer is on the gasoline side and the flow is turbulent, if the flow rate of gasoline is doubled, what will be the new exit temperature of the gasoline?
