Cp agua j/kg k
WebMapQuest WebGeothermal water (Cp = 4310 J/kg.K) with a mass flow rate of 0.37 kg/s is used to heat the water. It is accessible at 127degC. With a 0.8 cm diameter, the inner tube has thin walls. If the heat exchanger's overall heat transfer coefficient is 550 W/m2.K, calculate the length of the tube needed to provide the desired heating.

Water (liquid): CP = 4185.5 J⋅K −1 ⋅kg −1 (15 °C, 101.325 kPa) Water (liquid): CVH = 74.539 J⋅K −1 ⋅mol −1 (25 °C) For liquids and gases, it is important to know the pressure to which given heat capacity data refer. Most published data are given for standard pressure. See more In thermodynamics, the specific heat capacity (symbol c) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity. … See more The specific heat capacity of a substance, usually denoted by $${\displaystyle c}$$ or s, is the heat capacity $${\displaystyle C}$$ of a sample of the … See more International system The SI unit for specific heat capacity is joule per kelvin per kilogram J/kg⋅K, J⋅K ⋅kg . Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree … See more Relation between specific heat capacities Starting from the fundamental thermodynamic relation one can show, where, See more The specific heat capacity of a substance is typically determined according to the definition; namely, by measuring the heat capacity of a sample of the substance, usually with a See more The temperature of a sample of a substance reflects the average kinetic energy of its constituent particles (atoms or molecules) relative to its center of mass. However, not all … See more In theory, the specific heat capacity of a substance can also be derived from its abstract thermodynamic modeling by an equation of state and an internal energy function.
