Entry temperature of cold fluid Solution

STEP 0: Pre-Calculation Summary

Formula Used

Entry Temperature of Cold Fluid = Entry Temperature of Hot Fluid-(Heat exchanged/(Effectiveness of Heat Exchanger*Smaller Value))
t1 = T1-(Q/(ϵ*C_min))
This formula uses 5 Variables

Variables Used

Entry Temperature of Cold Fluid - (Measured in Kelvin) - Entry temperature of cold fluid is the temperature of the cold fluid at entry.
Entry Temperature of Hot Fluid - (Measured in Kelvin) - Entry temperature of hot fluid is the temperature of the hot fluid at entry.
Heat exchanged - (Measured in Watt) - Heat exchanged is the amount of heat transferred between two objects.
Effectiveness of Heat Exchanger - The effectiveness of heat exchanger is defined as the ratio of the actual heat transfer to the maximum possible heat transfer.
Smaller Value - Smaller value of mass flowrate of hot fluid * specific heat of hot fluid and mass flowrate of cold fluid * specific heat of cold fluid.

STEP 1: Convert Input(s) to Base Unit

Entry Temperature of Hot Fluid: 60 Kelvin --> 60 Kelvin No Conversion Required
Heat exchanged: 50 Watt --> 50 Watt No Conversion Required
Effectiveness of Heat Exchanger: 8 --> No Conversion Required
Smaller Value: 30 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t1 = T1-(Q/(ϵ*C_min)) --> 60-(50/(8*30))

Evaluating ... ...

t1 = 59.7916666666667

What is Heat exchanger

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.

How to Calculate Entry temperature of cold fluid?

Entry temperature of cold fluid calculator uses Entry Temperature of Cold Fluid = Entry Temperature of Hot Fluid-(Heat exchanged/(Effectiveness of Heat Exchanger*Smaller Value)) to calculate the Entry Temperature of Cold Fluid, Entry temperature of cold fluid formula is defined as the initial temperature of the cold fluid entering a heat exchanger, which is influenced by the heat transfer rate and the specific heat capacity of the fluid. Entry Temperature of Cold Fluid is denoted by t1 symbol.
