Which outcome results upon a sudden blockage of the turbine exhaust during a Rankine cycle?

A)Increased condenser heat rejection rate
B)Stalled turbine with adiabatic expansion
C)Vapor phase fluid accumulates upstream
D)Decreased boiler pressure due to backflow

💡 Explanation

Blockage causes fluid dynamic backpressure. Accumulation of liquid/vapor occurs, because the exhaust is unable to remove volume. Therefore, two-phase fluid accumulates upstream, rather than changes boiler pressure given feedwater control.
