Atmospheric pressure is the weight of the column of air over an area. For example, under standard conditions, the atmospheric pressure is 14.7 lbf/in.2 . This value means that the column of air in the atmosphere above a surface with an area of 1 in.2 will exert a force of 14.7 lbf. Convert the atmospheric pressure in the given units to the requested units: (a) 14.7 lbf/in.2 to lbf/ft2 , (b) 14.7 lbf/in.2 to Pa, (c) 14.7 lbf/in.2 to kPa, and (d) 14.7 lbf/in.2 to bars. Show all of the conversion steps. [Note: One Pascal (1 Pa) is equal to one newton per meter squared (1 Pa = 1 N/m2 ) and 1 bar = 100 kPa.]
