1. Design a 4-bit up/down Gray code counter using D flip-flops. It should count up when U = 1 and down when U = 0.
2. Design a 4-bit up/down Gray code counter using JK flip-flops. It must be able to count up when U = 1 and down when U = 0.
a tungsten wire 0.005mm in dia and 2 mm in length is placed horizontal in stagnant air. if we need to maintain the wire
Carbon dioxide (CO2) gas undergoes a process in a closed system from T1=100 F, p1=20 lbf/in^2 to T2=400 R,p2=50 lbf/in^2. The entropy produced due to internal irreversibilities during the process is determined to be 0.15 Btu/R per lb of gas.
