Solution

The correct option is B its specific volume increases
Specific volume is defined as the number of cubic meters occupied by one kilogram of a particular substance. When steam expands its volume increases hence its specific volume increases.

Q. Common Data:
Consider a steam power plant using a reheat cycle as shown. Steam leaves the boiler and enters the turbine at

4 M P a, 350^{o} C (h_{3} = 3095 k J / k g)

. After expansion in the turbine to

400 k P a (h_{4} = 2609 k J / k g

, the steam is reheated to

350^{o} C (h_{5} = 3170 k J / k G)

, and then expanded in a low pressure turbine to

10 k P a (h_{6} = 2165 k J . k g)
