Answer 2

Advantages and disadvantages of pressure velocity compounding

Advantages:

• Reliable and simple to operate.
• The leakage of steam is very less because of the low-pressure operation.
• The requirement of space and the initial cost is less due to lesser stages.
• No need to keep stronger blades because it works in lower pressure that reduces the stress.

Disadvantages:

• Due to high velocity, it has a high frictional loss.
• The consumption of steam is very high.
• To resist the high velocity the blades require specific designing and fabrication.
