Consider the complementary-bjt class b output stage and neglect the effects of finite vbe and vcesat . for ±10-v power supplies and an 8- load resistance, what is the maximum sine-wave output power available? what supply power corresponds? what is the power-conversion efficiency?
for output signals of half this amplitude,
find the output power, the supply power, and the power-conversion efficiency.

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.
