If a specimen of this steel is solutionized (aka, annealed to equilibrium) at 800°C, rapidly cooled to 550°C and is held at 550°C for 3 seconds, and is then quenched to room temperature, what constituents will make up the microstructure? a. Bainite and Martensite
b. Pearlite
c. Martensite
d. Austenite and Martensite
e. Austenite
f. Pearlite and Martensite
g. Austenite and Pearlite
h. Bainite

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
