The bridge rectifier in the circuit provides reverse polarity protection for the embedded system. Assume the embedded system needs 3.3 V to operate and all the diodes are Schottky diodes. Assume the embedded system draws an average of 10 mA. How much power is dissipated by the bridge rectifier if the battery voltage is large enough to power the system

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?
