Which of the following processes will tend to strengthen a typical pure metal ? Assume that we are comparing the stress-strain response of the original metal to the stress-strain responses of the room-temperature altered metals after these separate processes have been conducted. Select all that apply. Cold-working the pure metal. Hot-working the pure metal. Adding solute to form a solid solution. Precipitation of a secondary phase Annealing the pure metal. Melting then casting the pure metalIncreasing the dislocation density (dislocations count per unit volume) Decreasing the grain density (grain count per unit volume Increasing the average grain size

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.
