FAQs on Effectiveness when mc-cc is minimum value

What is the formula to find Effectiveness when mc-cc is minimum value?

The formula of Effectiveness when mc-cc is minimum value is expressed as Effectiveness of Heat Exchanger = (Mass Flow Rate of Cold Fluid*Specific heat of cold fluid/Smaller Value)*((Exit Temperature of Cold Fluid-Entry Temperature of Cold Fluid)/(Entry Temperature of Hot Fluid-Entry Temperature of Cold Fluid)). Here is an example- 10 = (500*2/30)*((25-10)/(60-10)).

How to calculate Effectiveness when mc-cc is minimum value?

With Mass Flow Rate of Cold Fluid (mc), Specific heat of cold fluid (cc), Smaller Value (C_min), Exit Temperature of Cold Fluid (t2), Entry Temperature of Cold Fluid (t1) & Entry Temperature of Hot Fluid (T1) we can find Effectiveness when mc-cc is minimum value using the formula - Effectiveness of Heat Exchanger = (Mass Flow Rate of Cold Fluid*Specific heat of cold fluid/Smaller Value)*((Exit Temperature of Cold Fluid-Entry Temperature of Cold Fluid)/(Entry Temperature of Hot Fluid-Entry Temperature of Cold Fluid)).

What are the other ways to Calculate Effectiveness of Heat Exchanger?

Here are the different ways to Calculate Effectiveness of Heat Exchanger-

Effectiveness of Heat Exchanger=Heat exchanged/(Smaller Value*(Entry Temperature of Hot Fluid-Entry Temperature of Cold Fluid))
Effectiveness of Heat Exchanger=(1-exp(-1*Number of Transfer Units*(1+Heat capacity ratio)))/(1+Heat capacity ratio)
Effectiveness of Heat Exchanger=(1-exp(-1*Number of Transfer Units*(1-Heat capacity ratio)))/(1-Heat capacity ratio*exp(-1*Number of Transfer Units*(1-Heat capacity ratio)))
