How to Calculate and Solve for Indicated Thermal Efficiency | Irrigation Water Requirement
Last Updated on April 20, 2024
The image above represents indicated thermal efficiency. To calculate indicated thermal efficiency, three essential parameters are needed and these parameters are Fuel Parameter (if), Mass of Fuel (mf) and Calorific Value (CV).
The formula for calculating indicated thermal efficiency:
ηi = if / mf . CV
Where:
ηi = Indicated Thermal Efficiency
if = Fuel Parameter
mf = Mass of Fuel
CV = Calorific Value
Let’s solve an example;
Find the indicated thermal efficiency when the fuel parameter is 28, the mass of fuel is 7 and the calorific value is 14.
This implies that;
if = Fuel Parameter = 28
mf = Mass of Fuel = 7
CV = Calorific Value = 14
ηi = if / mf . CV
That is, ηi = 28 / (7) . (14)
ηi = 28 / 98
ηi = 0.28
Therefore, the indicated thermal efficiency is 0.28.
Calculating the Fuel Parameter when the Indicated Thermal Efficiency, the Mass of Fuel and the Calorific Value are Given
if = ηi x mf . CV
Where;
if = Fuel Parameter
ηi = Indicated Thermal Efficiency
mf = Mass of Fuel
CV = Calorific Value
Let’s solve an example;
Find the fuel parameter when the indicated thermal efficiency is 20, the mass of fuel is 10 and the calorific value is 4.
This implies that;
ηi = Indicated Thermal Efficiency = 20
mf = Mass of Fuel = 10
CV = Calorific Value = 4
if = ηi x mf . CV
So, if = 20 x 10 . 4
if = 20 x 40
if = 800
Therefore, the fuel of parameter is 800.

Calculating the Mass of Fuel when the Indicated Thermal Efficiency, the Fuel Parameter and the Calorific Value are Given
mf = if / ηi x CV
Where;
mf = Mass of Fuel
ηi = Indicated Thermal Efficiency
if = Fuel Parameter
CV = Calorific Value
Let’s solve an example;
Find the mass of fuel when the indicated thermal efficiency is 2, the fuel parameter is 32 and the calorific value is 4.
This implies that;
ηi = Indicated Thermal Efficiency = 2
if = Fuel Parameter = 32
CV = Calorific Value = 4
mf = if / ηi x CV
So, mf = 32 / 2 x 4
mf = 32 / 8
mf = 8
Therefore, the mass of fuel is 8.
Calculating the Calorific Value when the Indicated Thermal Efficiency, the Fuel Parameter and the Mass of Fuel are Given
CV = if / ηi x mf
Where;
CV = Calorific Value
ηi = Indicated Thermal Efficiency
if = Fuel Parameter
mf = Mass of Fuel
Let’s solve an example;
Find the calorific value when the indicated thermal efficiency is 20, the fuel parameter is 4 and the mass of fuel is 3.
This implies that;
ηi = Indicated Thermal Efficiency = 20
if = Fuel Parameter = 4
mf = Mass of Fuel = 3
CV = if / ηi x mf
So, CV = 4 / 20 x 3
CV = 4 / 60
CV = 0.067
Therefore, the calorific value is 0.067.
