Conclusion:
From the Table A-2, "Ideal-gas specific heats of
various common gases" to obtain value of
3M0
density of air and the specific heat at the
average temperature of 15°C as 1.2 kg/m and
1.0 kJ/kg - °C.
Substitute 1.2 kg/m' for pair, 12 m for l, 2.3 m
for b, and 3.5 m for h in Equation (I).
(1.2 kg/m) x (12 m x 2.3 m × 3.5 m)truck
air =
(1.2 kg/m) x (96.6 m)
= 115.92 kg
