Consider the following statements:1. The duct may be made of galvanise...
Explanation:
The given statements are as follows:
1. The duct may be made of galvanised iron, aluminium, and fibre glass.
2. Fibre glass may be used in low-velocity applications.
3. The pressure in the ducts is usually expressed in mm of water.
4. High-pressure ducts are designed for static pressure up to 150 mm of water.
Valid Statements:
To determine which statements are valid, let's analyze each one individually.
1. The duct may be made of galvanised iron, aluminium, and fibre glass.
- This statement is valid as ducts can be made from these materials.
2. Fibre glass may be used in low-velocity applications.
- This statement is valid as fibre glass is commonly used in ducts for low-velocity applications. It provides insulation and is lightweight.
3. The pressure in the ducts is usually expressed in mm of water.
- This statement is valid as pressure in ducts is commonly expressed in mm of water. It is a unit of measurement used to quantify static pressure or pressure drop in duct systems.
4. High-pressure ducts are designed for static pressure up to 150 mm of water.
- This statement is valid as high-pressure ducts are designed to handle static pressures up to 150 mm of water. These ducts are constructed with stronger materials and are built to withstand higher pressures.
Conclusion:
Based on the analysis, the valid statements are:
a) 1, 2, and 3
Therefore, the correct answer is option 'B' - 1, 2, and 3.
The given statements are as follows:
1. The duct may be made of galvanised iron, aluminium, and fibre glass.
