With Throttle governing of a steam turbine, the turbine power is reduced by

Question

Direction: Each of the next consists of two statements, one labeled as the ‘Assertion (A)’ and the other as Reason (R)’ You are to examine these two statements carefully and select the answers to these items using the codes given below:

Codes:

1.  Both A and R are individually true and R is the correct explanation of A
2. Bothe A and R are individually true but R is not the correct explanation of A
3. A is true but R is false
4. A is false but R is true  

Assertion (A): With Throttle governing of a steam turbine, the turbine power is reduced by reduction in the available heat drop together with decrease in the rate of steam flow.     

Reason (R): The pressure and the rate of steam flow are simultaneously decreased with the help of a throttle valve.
