3. Mr. Britt is pouring a 36' x 58' concrete pad for a metal building. If concrete costs $123.00 per cubic yard, what will be the cost of the concrete to pour the pad 8 inches
thick? A cubic yard of concrete = 27 cubic feet and Cu. Ft. = T'x W' x L' (Round up
to the nearest cubic yard when calculating concrete needed.)
a. $5,047.00
b. $6,396.00
c. $6,564.00
d. $7,329.00

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

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
