Explanation:
According to the psychrometric chart at dry bulb temperature of and RH 70%, the absolute humidity = 0.011 kg/kg dry air
Formula to calculate humid volume is as follows.
dry air =
=
=
= 0.847 dry air
Hence, humid volume of air is 0.847 dry air.
Specific enthalpy of dry air = specific heat capacity of dry air × dry bulb temperature
=
= 21.126 kJ/kg dry air
Hence, the specific enthalpy of the air is 21.126 kJ/kg dry air.
As per the psychrometric chart at given conditions wet bulb temperature = 17.5
As per the psychrometric chart at given conditions dew point temperature = 15.5
Explanation:
1. Thermochemical equation is balance stoichiometric chemical equation written with the phases of the reactants and products in the brackets along with the enthalpy change of the reaction.
The given correct thermochemical reactions are:
2. Phase change affect the value of the enthalpy change of the thermochemical equation. This is because change in phase is accompanied by change in energy. For example:
In both reaction phase of water is changing with change in energy of enthalpy of reaction.
