Consider a normally-aspirated, four-stroke, spark-ignition, 1.8 L four-cylinder engine with a compression ratio of 10. The induction system uses a single throttle body, and the diameter of the throttle body is 42 mm. The air will enter the throttle body at P₁ = 80 kPa and T₁ = 290 K. The air will be throttled from the 80 kPa ambient pressure down to P₁ = 30 kPa in the intake manifold while the engine's crankshaft speed is 4200 rpm. Model the air as an ideal gas having constant specific heat, using 300 K values from Cengel's tables posted on Canvas. a) Find the temperature of the air in the intake manifold after the air is throttled from P₁ = 80 kPa to P₁ = 30 kPa (answer: T₁ = 288.91 K). b) Find the density and mass flow rate of the air in the intake manifold (answers: P₁ = 0.3618 kg/m³ and m = 0.02533 kg/s).
