Steam at 600. psia and 800.°F enters the high-pressure stage of an isentropic turbine and is reheated to 60.0 psia and 700.°F before entering the low-pressure stage. The steam then exhausts to a condenser at 1.00 psia. Neglecting pump power, determine
a. The isentropic Rankine cycle thermal efficiency.
b. The isentropic Rankine cycle thermal efficiency that would occur if the steam were not reheated.
c. The percent increase in thermal efficiency due to the reheating operation.
