How to Calculate Heat Exchanger Effectiveness?
Heat Exchanger Effectiveness calculator uses Effectiveness of Heat Exchanger=
if(Mass of hot fluid*Specific Heat Capacity of Hot Fluid>Mass of Cold Fluid*Specific Heat Capacity of Cold Fluid)
{
Effectiveness of Heat Exchanger=Mass of hot fluid*Specific Heat Capacity of Hot Fluid*(Inlet Temperature of Hot Fluid-Outlet Temperature of Hot Fluid)/(Mass of Cold Fluid*Specific Heat Capacity of Cold Fluid*(Inlet Temperature of Hot Fluid-Inlet Temperature of Cold Fluid))
}
else
{
Effectiveness of Heat Exchanger=Mass of Cold Fluid*Specific Heat Capacity of Cold Fluid*(Inlet Temperature of Cold Fluid-Outlet Temperature of Cold Fluid)/(Mass of hot fluid*Specific Heat Capacity of Hot Fluid*(Inlet Temperature of Hot Fluid-Inlet Temperature of Cold Fluid))
}
to calculate the Effectiveness of Heat Exchanger, The heat exchanger effectiveness is defined as the ratio of the actual heat transfer to the maximum possible heat transfer. . Effectiveness of Heat Exchanger and is denoted by ϵ symbol.
How to calculate Heat Exchanger Effectiveness using this online calculator? To use this online calculator for Heat Exchanger Effectiveness, enter Specific Heat Capacity of Cold Fluid (cc), Specific Heat Capacity of Hot Fluid (ch), Mass of hot fluid (mh), Mass of Cold Fluid (mc), Inlet Temperature of Cold Fluid (Tci), Inlet Temperature of Hot Fluid (Thi), Outlet Temperature of Hot Fluid (Tho) and Outlet Temperature of Cold Fluid (Tco) and hit the calculate button. Here is how the Heat Exchanger Effectiveness calculation can be explained with given input values -> -0.166667 =
if(10*10>10*10)
{
10*10*(35-20)/(10*10*(35-5))
}
else
{
10*10*(5-10)/(10*10*(35-5))
}
