Write an HDL code for an 32-bit Universal Shift Register with a positive-edge sensitive clock, a synchronous enable (highest priority), and an asynchronous negative-edge sensitive reset. The register can be loaded with serial in (1-bit) or parallel in (32-bit), and can be read serially (1-bit) or in parallel (32- bit). Also the register can perform left or right shift with a selection bit (1 for left shift, and 0 for right shift). b) Write a testbench for the module you wrote in (a) to test all of the corner cases.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
