The eta kappa nu (hkn) office sells sodas for 35 cents. suppose they install a soda controller that only takes the following three inputs: nickel, dime, and quarter. after you put in each coin, you push a pushbutton to register the coin. if at least 35 cents has been put in the controller, it will output a soda and proper change (if applicable). draw a finite state machine that describes the behavior of the soda controller. each state will represent how much money has been put in (hint: there will be seven of those states). once enough money has been put in it, the controller will go to a final state where the person will receive a soda and proper change (hint: there are five such final states). from the final state, the next coin that is put in will start the process again, contributing to the next purchase.

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?

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
