Specific heat is defined as the amount of energy needed to increase the temperature of a unit mass of a substance by one degree. The specific heat of water at room temperature is 4.18 kJ/kg · °C in SI unit system. Using the unit conversion function capability of EES, express the specific heat of water in
(a) kJ/kg K,
(b) Btu/lbm · F,
(c) Btu/lbm · R, and
(d) kCal/kg = · °C units.
