    4. To produce 1 kg of steam from a boiler determine the required quantity of heat at a pressure of 6 bar at a temperature of 25°C when it is superheated at a constant pressure at °C assuming the mean specific heat of superheated steam to be 2 kj/kgK.

    Thermophysical Properties of Fluid Systems. Accurate thermophysical properties are available for several fluids. These data include the following.   For all practical purposes you can determine the enthalpy of superheated steam by consulting its tabulated steam table available in any thermodynamic book. All you need to know is the pressure and temperature of the steam and read its correspondin.

Specific heat of superheated ammonia vapor Item Preview remove-circle. Isochoric specific heat (Cv) is used for ammonia in a constant-volume, (= isovolumetric or isometric) closed system. At ambient pressure and temperature the isobaric specific heat, C P, of ammonia is [kJ/kg K] or [Btu/lb °F] = [cal/g K], while the isochoric specific heat, C V, is [kJ/kg K] or [Btu/lb °F] = [cal/g K].

The bubble and dew point temperatures of the ammonia-water mixture have been determined from the equations (1) and (2). In this paper, NIST data sets have been used as a reference for specific volume and specific heat capacities for liquid and gas for both components, at the selected temperatures and pressures up to bar.

NIST contains data for superheated ammonia vapor up to °C. The saturation tables express all vapor states in terms of the specific volume [ft3/lb m]. The specific volume is inversely proportional to the fluid density (see definition above).

Cp (specific heat) Specific heat is a measure of the energy storing capability of the working fluid [Btu/lb m-R]. Fluids with large specific heats require significant. Calculate online thermodynamic and transport properties of ammmonia based on industrial formulation (formulated in Helmholtz energy) for advanced technical applications.

Both phases, liquid and vapor, were present and in equilibrium. A correction was made for the mass of the liquid, using the results obtained from a separate determination of the specific volume of the liquid (already published).

The vapor was superheated about o. T C. in order to prevent condensation taking place on the walls of the picnometers. Specific Heat Capacity of Liquid Water: = kJ/kg.

Refrigerant that has boiled (turned into a vapor) at 40 degrees has a saturation temperature of 40 degrees. If the refrigerant vapor is heated to 41 degrees it is no longer saturated, it is then superheated by 1 degree.

Remember, only a gas or vapor can be superheated. Superheat is any temperature of a gas or vapor above its saturation temperature.Table A Properties of Superheated Ammonia Vapor Table A Properties of Saturated Propane (Liquid–Vapor): Temperature Table Table A Properties of Saturated Propane (Liquid–Vapor): Pressure Table Table A Properties of Superheated Propane Vapor Table A Properties of Selected Solids and Liquids: c p, r, and k.
