An air compressor intakes atmospheric air at 14.7 psi and increases its pressure to 150 psi (gauge). The pressurized air is stored in a horizontal tank. What is the absolute pressure of air inside the tank? Express your answers in: (a) psi, (b) kPa, (c) bar, and (d) standard atm (recall that 1 atm =14.7 psi = 101.325kPa).
