What is ntu in thermodynamics?
NTU is nothing but Number of Transfer Units. It is one of the method used to find the heat transfer of hot and cold body it is applicable to both parallel and counter flow.============The NTU Method is used to calculate the rate of heat transfer in heat exchangers when there is insufficient information to calculate the Log-Mean Temperature Difference (LMTD). If fluid inlet and outlet temperatures are specified or can be determined by simple energy balance, the LMTD method should be used; but when these temperatures are not available The NTU or The Effectiveness method is used. It is based off of the maximum possible heat exchange in an infinitely long heat exchanger. From this, different heat exchangers can be compared and estimates of actual heat exchange calculated based on the NTU effectiveness.
What are the units used to measure heat conductivity?
The units used to measure heat conductivity are watts per meter-kelvin (W/mK).
What materials transfer heat the best?
Materials that conduct heat well, such as metals like copper and aluminum, transfer heat the best. These materials have a high thermal conductivity, allowing them to efficiently transfer heat from one point to another. Insulating materials, on the other hand, do not transfer heat well and are used to reduce heat transfer.
What heat transfer is being used when a heat lamp is heating a box?
The heat transfer being used in this scenario is radiation. The heat lamp emits infrared radiation that is absorbed by the box, causing its temperature to increase.
What type of heat transfer is used in curtains?
Conduction is the main type of heat transfer used in curtains. The material of the curtain absorbs and conducts heat, which helps to regulate the temperature in the room by either retaining or blocking heat.
Why are coolants used in nuclear power industries?
To transfer the heat produced in the fuel to the steam raising units.
Where in the house is a heat pump used?
A heat pump is often used in air conditioning units and refrigerators because a heat pump is used to transfer heat from one place to another. Often heat pumps are used to remove heat from a building
What Units used to express energy transfer?
Its the exact amount without loosing any in the process. This process is called "The Law of Conservation of Energy".
What units are used to express distance?
metre
What is the units of measuer ment that are used to measuer earths heat?
Units commonly used to measure Earth's heat include degrees Celsius (°C) or Kelvin (K) for temperature measurements, joules (J) or calories (cal) for heat energy, and watts per square meter (W/m^2) for heat flux or heat transfer rates.
