Because the temperature change that occurs across the heat exchanger from the entrance to the exit is not linear, and a logarithmic function best describes this temperature change.

Which type of temperature senseing instrument you use in industry?
for temperature sensing i will suggest a RTD or A THermocouple. for temperature sensing i will suggest a RTD or A THermocouple.
How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
Why can a semiconductor measure temperature?
Semiconductor resistance depends on temperature. So, you can use a shunt resistor to measure semiconductor voltage with a given current and, then, obtain temperature.
What tool would you use to determine the temperature of a liquid?
Thermometer
Why do BP use cement instead of concrete to seal boreholes?
When I heard this I just assumed people were saying cement to mean they were using concrete. In my experience most people do not know the difference.
Why you we use log mean temperature difference formula?
The use of the LMTD arises straightforwardly from the analysis of a heat exchanger with constant flow rate and fluid thermal properties. It is a simple method to approximated the temperature diving force in a heat exchanger. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. The larger the LMTD, the more heat is transferred.
Why do you use lmtd?
'Lmtd' might be okay in a text message. Otherwise, it's lazy - use 'limited.'
What do you use a THermocouple for?
measuring temperature difference
What is the use of water discharged from AC?
The water from an air conditioner you are referring to is known as condensation. This occurs when there is a difference in temperature between an object and the temperature of the air.
Is temperature a source of energy?
No. Temperature is a measurement of atomic or molecular movement. If you have a difference in temperature between two things, you could use the difference, (and reducing the difference) to get energy, To put it simply, if you have a hot item and a cold item, you can take the difference to make electricity. If you are in a desert, and everuthing has the same temperature, you can't. Similarly, the weights on a clock gives energy to the movement of the clock, until they reach the floor, then all the potential energy has been transformed into kinetic (movement) energy in the clock, and finally to heat due to friction.
What is apparatus dew point?
A pair of bulbs for measuring temperature and one is wet ted to give the temperature difference when it is spun in the air to cool the bulbs, or you can use a pressure vessel type with a mirror
What does difference mean in an math equation?
Difference in math means subtraction. To express the difference between 6 and 2 you would use the equation 6 - 2 = 4.
What is difference in Continue using vs continue to use?
There isn't a difference in the statements continue using and continue to use. Both mean to keep going and not stop using a specific item.
Does difference mean subtract or divide?
You would use subtract to find the difference between values, by subtracting the lower value from the higher one.
What is the primary meaning and or use of measurement of Delta T?
Normally the term " delta T" is used to indicate the difference of two temperature readings.
Is Fahrenheit an English temperature unit?
If by English you mean American then yes, in London I believe they use Celsius.
What are the unit use for measuring the use in the temperature?
There are no units for measuring the use of temperature.
