[Hint: This question has no numbers. Your answer needs to be an equation.] Submission status3 A fluid of density 1200 kg/m° at 1 atm pressure is compressed to 101 atm pressure isothermally. If the isothermal compression is 4.8, 105 atm. -1 the 3. increase in density in kg/m of fluid is1. Suppose you are flying a 7,784 kilograms aircraft at 14,630 meters where the air density is 0.2062 kilograms/cubic meter.
