12.1 A class A emitter follower, biased using the circuitshown in Fig. 12.3, uses Vcc=10V, R = RL=\kQ., withall transistors (including Q3) identical. Assume V££ = 0.7 V, VC£sat = 0.3 V, and ft to be very large. For linear operation, what are the upper and lower limits of output voltage, andthe corresponding inputs? How do these values change if theemitter-base junction area of Q3 is made twice as big as thatof S2? Half as big?

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
