Our diodes are connected in parallel: anodes joined together and fed with a constant current I, and cathodes joined together and connected to ground. What relative junction areas should these diodes have if their currents must have binary-weighted ratios, with the smallest being 0.1 mA? What value of I is needed?

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.
