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 (c_{c}), Specific Heat Capacity of Hot Fluid (c_{h}), Mass of hot fluid (m_{h}), Mass of Cold Fluid (m_{c}), Inlet Temperature of Cold Fluid (T_{ci}), Inlet Temperature of Hot Fluid (T_{hi}), Outlet Temperature of Hot Fluid (T_{ho}) and Outlet Temperature of Cold Fluid (T_{co}) 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))
}
