A.Assertion (A): Nozzle control governing cannot be used in reaction steam turbines.
Reason (R): In reaction steam turbines, full admission of steam must take place.
(a) Both A and R are true and R is a correct explanation of A
(b) Both A and R are true but R is not a correct explanation of A
(c) A is true but R is false
(d) A is false but R is true
B. Throttle governing in steam turbines
(a) Leads to significant pressure loss (b) Increases the efficiency
(c) Increases heat losses (d) Decreases steam temperature
C. Willian’s line represents
(a) Total steam consumption vs. power output with throttle governing
(b) Total steam consumption vs. power output with cut-off governing
(c) Behaviour of supersaturated steam through nozzles
(d) Condensation of steam while flowing through the turbine
