2. Design a three-bit counterlike circuit controlled by the input w. If w = 1, then the counter adds 2 to its contents, wrapping around if the count reaches 8 or 9. Thus if the present state is 8 or 9, then the next state becomes 0 or 1, respectively. If w = 0, then the counter subtracts 1 from its contents, acting as a normal down-counter. Use D flip-flops in your circuit.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
