What is the formula for specific heat?
The formula for specific heat capacity, C , of a substance with mass m , is C = Q /(m ⨉ ΔT) . Where Q is the energy added and ΔT is the change in temperature.
What is CP of steam?
Steam Cp=1.8723 kJ/kg. K Cv=1.4108 kJ/kg.
What is the specific heat of steam in Btu?
1150.4 BTU per
It is convenient for finding the amount of heat needed for certain processes. From Table 1, total heat of steam at atmospheric pressure (0 psig. or 14.696 psia) is given as 1150.4 BTU per Lb.
What is the specific heat of Vapour?
1.996 kJ/kgK
Explanation: The specific heat capacity, or the amount of heat needed to raise the temperature of a specific substance in a specific form one degree Celsius, for water is 4.187 kJ/kgK, for ice 2.108 kJ/kgK, and for water vapor (steam) 1.996 kJ/kgK.
How do you calculate specific heat?
Specific heat is the quantity of heat essential to raise the temperature of one gram of any substance by 1 degree Celsius. Specific Heat formula is articulated as. Where, Δ Q is the heat gained or lost. Δ T is the temperature difference. m is the mass. The temperature difference is given by Δ T = (T f – T. i.
What is the specific heat capacity of steam?
The specific heat capacity (cp) for steam is highly variant, depending on the actual temperature of the steam. At about 125 °C it’s about 1.9 kJ/ (kg*K). [1] That means, in disregard to its actual preassure/volume/density, it takes 1.9 kJ to raise the temperature 1 K further per kg of steam.
What is specific heat of a substance?
Specific heat is the quantity of heat essential to raise the temperature of one gram of any substance by 1 degree Celsius. . Specific Heat formula is made use of to find the specific heat of any given material, its mass, heat gained or temperature difference if some of the variables are given.
What is the SI unit of specific heat of water?
S.I unit of specific heat is J kg-1 K-1. For liquid at room temperature and pressure, the value of specific heat capacity (C p) is approximately 4.187 kJ/kgK. For ice 2.108 kJ/kgK. For water vapor (steam) 1.996 kJ/kgK. Was this answer helpful?
