Design the circuit of fig. 9.14 to provide a differen- tial output voltage (i. e., one taken between the two collectors) of 1 v when the differential input signal is 10 mv. a current source of 1 ma and a positive supply of +5 v are available. what is the largest possible input common-mode voltage for which operation is as required? assume α 1.

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.
