Design an 8-bit left shifter using only 24 2:1 multiplexers. The shifter accepts an 8-bit input A and a 3-bit shift amount, shamt2:0. It produces an 8-bit output Y. Sketch the schematic. An incrementer adds 1 to an N-bit number. Build an 8-bit incrementer using half adders. Build a 32-bit synchronous Up/Down counter. The inputs are Reset and Up. When Reset is 1, the outputs are all 0. Otherwise, when Up

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
