The owner of the theater will never change the number of rows or number of seats in a row. Therefore, when you write your class, you also must create two additional data fields that are constants. Each data field will represent the number of rows or number of columns in your array. Give them a useful name so the reader of your program understands what these values represent. Remember that, as a matter of convention, constant values are written in ALLCAPS, tagged as "static final" and placed so that their scope is the scope of the whole driver class. The ALLCAPS makes it easier for us to quickly read our own code. The "static" tag makes these constant values accessible in both static and non-static methods (in both class and instance methods). The "final" tag means that this value cannot be changed. A

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?

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
