Calculate the total quantity of bricks, with 2% waste factor, required to be placed in a foundation wall, whose Perimeter of the Wall is 207 ft 4 in.; Height of Wall is 9 ft.; and 8" Wall Thickness, using Common Bond. There are 9 Windows that are 4 ft. by 4 ft. and 1 door that is 4 ft. by 6.5 ft high. Given: Brick size is 8" x 2-1/4" x 3-3/4"
Size of Mortar Joint is 1/2"

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
