Design a Moore type synchronous state machine with three external inputs A1, A2, A3 and
one output signal F. The output F goes to 1 when A1.A2.-A3 = 1 at the next system timing
event. The output F stays at 1 as long as A3=0; otherwise, the output goes to 0. (Note: use
a positive edge-triggered D flip-flop in the design)

A pump draws water through a 300-mm diameter cast iron pipe, 15m long from a reservoir
in which the water surface is 4.5 m higher than the pump and discharges through a 250-
mm diameter cast iron, 75 m long, to an elevated tank in which the water surface is 60 m
higher than the pump. Q=0.25 m³/s. Considering f-0.02 and the coefficients for minor
head losses (k entrance 0.5, k bend 0.35, and K exit -0.5), compute the power of the pump.
