What is sensible heat formula?
What is sensible heat formula?
The sensible heat formula is used to calculate the flow of air in the electric furnace. The sensible heat formula with a change in temperature is expressed as. Q sensible= 1.10 x cfm x (to – ti)
What is the sum of sensible and latent heat?
Enthalpy
Enthalpy is the sum of the sensible and latent heat in a given air-vapor mix. It is sometimes referred to as the total heat of the air. The units for sensible heat, latent heat, and enthalpy are the same: BTU/lb of dry air.
Where does 1.08 come from HVAC?
In simple terms the factor of 1.08 is the product of the specific heat (0.24 BTU) times the density (0.075 lbs cubic foot) times the number of minutes per hour (60 min/hour). The factor 1.08 assumes standard conditions at the blower (70 degrees F and sea level).
What is difference between sensible heat and latent heat?
The main difference between the sensible and latent heat is that: Sensible heat relates to the change in temperature of an object or gas without a change in the phase. But, latent heat relates to the change in phase between solids, liquids, and gases.
What is L in latent heat?
A specific latent heat (L) expresses the amount of energy in the form of heat (Q) required to completely effect a phase change of a unit of mass (m), usually 1kg, of a substance as an intensive property: Intensive properties are material characteristics and are not dependent on the size or extent of the sample.
What is the unit of latent heat?
The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance undergoing a change of state.
What is latent heat and write formula?
The latent heat formula is given by, L = Q / M. Where, Q = amount of heat. M = mass of the substance.
What is the difference between latent and sensible heat?
Latent and sensible heat are types of energy released or absorbed in the atmosphere. Latent heat is related to changes in phase between liquids, gases, and solids. Sensible heat is related to changes in temperature of a gas or object with no change in phase.
