What is the specific heat capacity of steam in J kg C?
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.
What is the CP value of steam?
1.8723 kJ/kg.
Steam Cp=1.8723 kJ/kg. K Cv=1.4108 kJ/kg.
How do you calculate steam heat capacity?
Explanation: First, the water must be heated to 100 degrees celcius and then the 100 degree water must be turned into steam. Using the equation Q=mcΔT we can calculate the amount of energy for heating the water to 100 degrees. c=4187 Joules per kilogram- the specific heat capacity of water.
What is the specific heat capacity of water Vapour?
Specific heat water vapor: 1.996 kJ/kgK =0.4767 Btu(IT)/(lbm °F) or kcal/(kg K)
What is the value of specific heat of vaporization of steam?
It is defined as the amount of heat needed to raise the temperature of a specified amount of a specific substance one degree Celsius period for water that is 4.2 kJ/kg/°K for ice that is 2.1 kJ/kg/°K for water vapor steam that is 1.996 kJ/kg/°K.
What is specific heat capacity of glass?
The specific heat capacity of a type of glass is 840 J kg-1 °C-1. This means that 840 J of heat is required to raise the temperature of 1 kg of the glass by 1 °C.
What is the heat capacity of steam in joules?
Heat Capacities for Some Select Substances
| Substance | specific heat capacity Cp,s (J/g °C) | molar heat capacity Cp,m (J/mol °C) |
|---|---|---|
| titanium | 0.523 | 26.06 |
| water (ice, O°C) | 2.09 | 37.66 |
| water | 4.184 | 75.38 |
| water (steam, 100°C) | 2.03 | 36.57 |
What is VF and VG in steam table?
vf = Specific volume of saturated water (liquid). vg = Specific volume of saturated steam (gas).
What is the specific heat capacity of ceramic?
1.49 kJ/kgБK
The specific heat capacity of the clay ceramic increased from 1.20 to 1.49 kJ/kgБK for a 30 wt\% addition of biochar.
Which has a highest specific heat capacity?
Water has the highest specific heat capacity. It therefore takes a long time to heat and long time to cool. The following uses/ effects are due to the high specific heat capacity of water.
What are some examples of specific heat capacity?
An example: the specific heat of water is 1 calorie/gram °C = 4.186 joules/gram °C which is higher than any other common substance. Because of this, water plays a very important role in temperature regulation. The specific heat per gram for water is much higher than that for a metal.
What is the formula for specific heat capacity?
The formula for specific heat capacity is q=mcΔT. “Q” stands for heat, usually given in Joules. “m” is the mass of the given substance. “c” is the specific heat capacity of that substance, and “ΔT” is the change in temperature (initial temperature minus final temperature) in degrees Celsius . Specific…
What is the specific heat ratio of steam?
The ratio of specific heats for steam ranges from 1.3 to 3.0 at different pressures and temperatures. Steam is a very non-ideal gas and the Cp/Cv ratio should not be used. The actual isentropic exponent varies only slightly from 1.3.
