Cp water as function of temperature

Melting temperature (at 10kPa): °C = 32°F. Liquid water properties at temperatures between melting point and boiling point. Density, specific heat , viscosity and thermal conductivity of liquid water at atm.


Dynamic viscosity: The viscosity of a fluid characterizes the resistance to the movement of the fluid. This page provides supplementary data to the article properties of water.

Further comprehensive authoritative data can be found at the NIST Webbook page on thermophysical properties of fluids. Except where noted otherwise, data relate to standard ambient temperature. Helmholtz energy as a function of temperature and density,. Similar equations for the specific heat capacity at constant pressure and. Polynomial temperature functions for specific volume equation a. Dependence of the isobaric specific heat capacity of water vapor on the pressure and.


The CV values for supercooled water may . Equations of properties as a function of temperature for seven fluids.

Freon-1 engine oil, and mercury. C, or centipoise at °C. Heat capacity , thermal conductivity, and density of whole milk, skimmed milk, and.


Water has a viscosity of 0. Total energy to raise temperature of 1. At a certain location the temperature of the water supply is 2K. Specific heat : = energy required to change a unit mass of a material by 1°C. Prove that the specific heat at constant pressure, for an ideal gas is a function.


Then, the relation of water temperature to time Tw(t) is measure the water being. Thermal conductivity and specific heat at various temperatures and water contents . On the other han when the temperature drops and water freezes, water molecules form a crystal . Eyeball a best fit function to the the water -heating-up data for each experiment. The specific heat capacity (Cp) of liquid water at room temperature and. Except for gases, the temperature and volume dependence of the specific heat of most substances is weak.


We see from this table that the specific heat of water. The table following gives the values of specific heat capacities as a function of temperature.

We find that choosing values of specific heat. Alternatively, heat capacity of liquids is essential when sizing heat . For example, the O-H bonds in water can stretch and ben and the whole molecule . As an example, consider the difference between temperature (units of K) and. By definition, the heat capacity of water at 15°C is cal K -g -or cal K -. Heat capacities are measured by calorimetry and often fit by a function of the form.
