Find the value of IC1 and IC2 , and state the operating mode of each transistor. Hint: make a list of all possible combinations of operating modes for the transistors and by the process of elimination using KVL/KCL, there should be one possible combination. E. g. if the bottom transistor is off, can the top transistor be in forward active?

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.
