Design a 4-bit synchronous up/down counter using combinational logic and dffs resettable to zero, with inputs: clk, reset, and inc/dec, and output: count(3: 0), such that upon reset count = "", count++ = count- – „1‟ when inc/dec = „0‟, and count = count- + „1‟ when inc/dec = „1‟. when inc/dec = „1‟ and count- = "", count+ = ""; and when inc/dec = „0‟ and count- = "", count+ = "".

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
