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.

What is an example of sensible heat?

Sensible heat is literally the heat that can be felt. It is the energy moving from one system to another that changes the temperature rather than changing its phase. For example, it warms water rather than melting ice. ... In figure 2, very cold ice has heat added to it.

How is latent heat different from sensible heat provide an example of each?

Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. ... Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.

What is the difference between sensible and latent loads?

Regarding HVAC, latent energy essentially refers to the relative humidity or moisture in the air. A high latent load would mean that the relative humidity was high. Sensible energy is the energy that alters the mean radiant temperature (MRT) and air temperature that you can feel.

What is the difference between sensible and non sensible heat?

What is the difference between sensible and non sensible heat? Sensible heat is heat that is gained or loss measured by a thermometer or other device. Non sensible is heat that is loss during water freezing is not able to be measure by a thermometer.

What are two types of latent heat?

Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling). These names describe the direction of energy flow when changing from one phase to the next: from solid to liquid, and liquid to gas.

What is latent heat in simple words?

Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. ... 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.

Can you feel latent heat?

When it's really humid inside your home, you probably feel a lot of latent heat in addition to sensible heat.

How do you calculate latent heat?

Latent heat calculation

The specific latent heat is different for solid to liquid transition and liquid to gas transition. For example, if we want to turn 20 g of ice into water we need Q = 20 g * 334 kJ/kg = 6680 J of energy. To turn the same amount of water into vapor we need Q = 45294 J .

What do you get when you mix sensible and latent heat?

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.
