(1) create three files to submit: itemtopurchase. h - struct definition and related function declarations itemtopurchase. c - related function definitions main. c - main() function build the itemtopurchase struct with the following specifications: data members (3 pts) char itemname [ ] int itemprice int itemquantity related functions makeitemblank() (2 pts) has a pointer to an itemtopurchase parameter. sets item's name = "none", item's price = 0, item's quantity = 0 printitemcost() has an itemtopurchase parameter. ex. of printitemcost() output: bottled water 10 @ $1 = $10

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?
