Introduction:
Heat exchangers are devices that transfer thermal energy between two or more fluids at different temperatures. The degree of approach in a heat exchanger refers to the temperature difference between the outlet temperatures of the hot medium and the cold water.
Explanation:
The degree of approach is an important parameter in heat exchanger design and operation. It indicates how effectively the heat exchanger is transferring heat from the hot medium to the cold water. The closer the outlet temperatures of the hot medium and the cold water, the higher the degree of approach, and the more efficient the heat transfer.
Definition:
The degree of approach is defined as the temperature difference between the outlet temperature of the hot medium and the outlet temperature of the cold water in a heat exchanger.
Significance:
The degree of approach is a crucial factor in determining the performance and efficiency of a heat exchanger. It affects the overall heat transfer rate, the size of the heat exchanger, and the energy consumption. A higher degree of approach indicates a more efficient heat transfer process.
Calculation:
To calculate the degree of approach, we need to know the outlet temperatures of the hot medium and the cold water. Once we have these values, we subtract the outlet temperature of the cold water from the outlet temperature of the hot medium.
Degree of Approach = Outlet Temperature of Hot Medium - Outlet Temperature of Cold Water
Correct Option:
In the given options, option 'D' states that the degree of approach is the difference between the outlet temperatures of the hot medium and the cold water. This is the correct answer because it aligns with the definition and calculation of the degree of approach in a heat exchanger.
Conclusion:
The degree of approach is a crucial parameter in heat exchanger design and operation. It represents the temperature difference between the outlet temperatures of the hot medium and the cold water. By understanding and optimizing the degree of approach, engineers can design more efficient heat exchangers that maximize heat transfer and minimize energy consumption.
