The specific enthalpy of liquid n-hexane at 1 atm varies linearly with temperature and equals 25.8 kJ/kg at 30C and 129.8 kJ/kg at 50C. (a) Determine the equation that relates H(kJ/kg) to T(C) and calculate the reference temperature on which the given enthalpies are based. Then derive an equation for U(T)(kJ/kg) at 1 atm. (b) Calculate the average heat transfer rate required to cool 20 kg of liquid n-hexane from 80C to 20C in 5 min.
