Steam is the ultimate destination for playing discussing and creating games. 22064 MPa Critical Temperature 37395C.
The steam must be reheated or superheated in order to avoid damages that could be caused to blades of steam turbine by low quality steam.
Cp of superheated steam. Specific Heat of Superheated Steam. Viscosity of Superheated Steam. MPa s Pa s cP kgf sm² lbf sin².
The superheated steam region depicts steam at a temperature higher than its saturation temperature. Should saturated steam be heated at constant pressure its temperature will rise producing superheated steam. Set your preferences for these steam tables.
- You cannot use commas as decimal points. Please use periods. Specific Enthalpy of Super Heated Steam can be calculated from the regular equation hs hg Cp Ts - Tf Cp - Specific Heat of Steam at Constant Pressure which can be considered as 1860 KJKgC Ts - Temperature of super heated Steam T f - Saturation temperature ie 100C.
TurestillthewellknownvaluehederivedCp048hasbeen acceptedgenerally forall temperatures and pressures. Laterdeterminationswhich have been made show thatCp varies. H superheated h sat.
Vapor T_sat for given boiler P Cp T_steam - T_sat The issue came up when evaluating specific heat constant for superheated steam. I used Shomates Equation. Cp A Bt Ct2 Dt3 Et2.
You may use this calculator to find Cp of Saturated Superheated stem. Online calculation of properties of water and steam For normal calculations Saturated Steam at Atmospheric pressure you may take value of Cp for steam as 2 kJkgK.

At atmospheric pressure 0 bar g absolute 1 bar water boils at 100 o C and 41751 kJ of energy is required to heat 1 kg of water from 0 o C to evaporating temperature 100 o C. 22064 MPa Critical Temperature 37395C. Ideal Gas Constant of Steam.
R 04615 kJkgK. Specific Heat Capacity of liquid water. C H2O 418 kJkgC.
Specific heat C is the amount of heat required to change the temperature of a mass unit of a substance by one degree. Isobaric specific heat Cp is used for substances in a constant pressure ΔP 0 system. Isochoric specific heat Cv is used for substances in a constant-volume.

High content of water droplets can cause the rapid impingement and erosion of the blades which occurs when condensed water is blasted onto the blades.
To prevent this condensate drains are installed in the steam piping leading to the turbine. The reheater heats the steam point D and then the steam. Where to find Cp values for steam for different pressures at different temperatures.
I can not find a table for water vapour for Specific heat at const. Pressure values for at varying temperatures. Callendarholds thatatzero pressure C should havea constant value but Knoblauchand Jakob fromtheirdirectdetermin-.
Blue - viscosity of water 1 Supercritical fluids are phases of substances at high pressures above their critical temperatures. Supercritical water is superheated steam under high pressure of more than 32062 psia 200 atm. Under these conditions supercritical water decomposes to many substances.
