You drive on 15 to the Bay Area. Midway through the trip your car indicates that the tire
pressure is low. The pressure is supposed to be 330 kPa (absolute) but you measure it to
be 290 kPa. Due to driving, the temperature of the air in the tires when they are filled is
50 °C. You add air to the desired pressure value for your tires and keep driving. The next
morning, the air in the tires has equilibrated to San Francisco morning temperatures of 10
°C, and your car still says the tire pressure is low. Assume the tire volume to be fixed. Take
C₂ = 1.005 kJ/kg-K and C₂ = 0.718 kJ/kg-K, T = 132 K, and Pc = 3.77 MPa.
(a)
In words, describe why the tire pressure is low the next morning, even though
you filled up the tires midway through your trip.
(b)
(c)
(d)
(e)
Sketch a T - v diagram of the process.
Determine whether the ideal gas law is appropriate to employ for further
analysis in this situation. Your argument should involve numbers.
Calculate the pressure of the tires the next morning…
(b)
The aircraft's Indicated Air Speed is 150 KIAS. Find the corresponding values
of True and Equivalent Air Speeds if the Flight Manual shows CAS to be 2
knots less than IAS under those conditions. Give your answers in both m.s¹ and
knots
