## What is latent heat of condensation?

As the latent heat of steam at atmospheric pressure is 2257 kJ/kg the amount of flash steam produced will be 299/2257 = **0.133 kg/kg** of condensate.

## What is the formula for latent heat of condensation?

Q2. What is the Specific Latent Heat of a Material? Ans: Specific latent heat is denoted by L and it is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change. It can be defined through the formula: **Q=mL** and its SI unit is Joule per kilogram (J/kg).

## How do you calculate latent heat of steam?

Latent Heat **( he ) = hg - hf = 2676 - 419 = 2257 KJ / Kg**. Cp - Specific Heat of Steam at Constant Pressure, which can be considered as 1.860 KJ/Kg. °C, Ts - Temperature of super heated Steam, Tf - Saturation temperature i.e., 100°C.Apr 24, 2016

## How do you calculate the heat of condensation in a steam?

Calculate the total condensed liquid flow based on the heat load from the process reactor. This is determined by **dividing the total heat removed by the system by the latent heat contained in the steam**. The calculation is 30,000 / 794, which is 37.8 lb/hr of liquid condensate.Mar 13, 2018

## What is latent heat of fusion and vaporization?

Latent heat of fusion is **the amount of heat that a solid substance requires to change its phase from solid phase to liquid phase at a constant temperature** while Latent heat of vaporization is the amount of heat that a liquid substance requires to change its phase from the liquid phase to vapor phase at a constant ...May 28, 2018

## Is latent heat of vaporization same as latent heat of condensation?

The latent heat of condensation has **the same value as the latent heat of vaporization**, but heat is released in the change in phase from vapor to liquid.

## What is L * latent heat?

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.Nov 6, 2021

## What is latent heat of condensation Upsc?

So latent heat of condensation is **the heat released when gases turn into liquid**.

## What is the formula for latent heat of vaporization?

Hence, we can conclude that The specific latent heat (L) of a material: It is a measurement of the amount of heat energy (Q) emitted or absorbed per mass (m) during a phase shift. The formula **Q = mL** is used to describe it.

## What is mean by latent heat of steam?

Latent heat of steam is commonly known as **the latent heat of vaporization**. Latent heat of vaporization is the amount of heat required to convert 1 Kg of liquid to vapour or steam. The value of latent heat is the property of the individual substance and it varies depending on the substance.
