A tyre is filled with air at 14.9 degree C to a gauge pressure of 231 kPa. If the tyre reaches a temperature of 37.5 degree C, what fraction of the original air must be removed if the original pressure of 231 kPa is to be maintained?© BrainMass Inc. brainmass.com June 3, 2020, 6:22 pm ad1c9bdddf
In the present problem following data is given :
Initial temperature T1 = 14.9OC = 14.9 + 273 = 287.9 K
Final temperature T2 = 37.5OC = 37.5 + 273 = 310.5 K
Initial pressure P1 = 231 kPa = 231 x 103 Pa
Final pressure P2 = Initial pressure P1 ...
Problem is solved with application of perfect gas equation.
