BlakeTerminal temperature difference (TTD) is the temperature difference between the hot and cold streams at the end of a heat exchanger. It is a critical parameter in the design and operation of heat exchangers, as it directly affects the rate of heat transfer and the overall efficiency of the system. A smaller TTD generally leads to a more efficient heat transfer process.

How do you find the difference in temperature?
To find the difference in temperature between two values, subtract the smaller temperature from the larger temperature. The result will give you the difference in temperature.
Can terminal potential difference be greater than the emf supplied?
No, the terminal potential difference cannot be greater than the emf supplied. The emf represents the maximum potential difference that the cell or battery can provide, while the terminal potential difference is the actual potential difference across the terminals when a load is connected.
How do you induce polarity in galvanometer?
To induce polarity in a galvanometer, you can connect the positive terminal of a power source to one terminal and the negative terminal to the other terminal. This creates a potential difference across the terminals of the galvanometer, inducing polarity in the device.
What is the difference between terminal speed and terminal velocity?
Terminal speed refers to the constant speed of an object falling through a fluid when the force of air resistance equals the force of gravity. Terminal velocity, on the other hand, is the maximum speed reached by an object falling through a fluid when it stops accelerating due to air resistance. Terminal velocity is a specific type of terminal speed.
Is energy only transferred by heating if there is no temperature difference?
No, energy can still be transferred by heating even when there is a temperature difference. Heat will flow from the object or system with higher temperature to the one with lower temperature until thermal equilibrium is reached. The temperature difference determines the direction and rate of heat transfer.
