Turbo Physics Grade 12 Pdf 〈2025-2026〉

T₂ = 298 K × (1.8/1.0)^0.286 T₂ = 298 × 1.8^0.286 1.8^0.286 ≈ 1.178 T₂ ≈ 351 K → 78°C (theoretical ideal).

“More air means more fuel can be burned,” Kael said. “That’s the power gain.” But 135°C air caused engine knock. Dr. Vane handed him an intercooler—an air-to-air radiator. After the intercooler, temperature dropped to 45°C while pressure only dropped to 1.7 atm. turbo physics grade 12 pdf

His mentor, an old turbine specialist named Dr. Vane, handed him a rusted turbocharger from a derelict freight hauler. “Fix this,” she said, “and you’ll understand more than any textbook.” T₂ = 298 K × (1

T₂ = T₁ × (P₂/P₁)^((γ-1)/γ)

Without turbo, ambient air density was 1.18 kg/m³. Density ratio = 1.56/1.18 = 1.32 → 32% more air molecules. His mentor, an old turbine specialist named Dr

To reduce lag, Kael lightened the turbine wheel (lower I) and designed a smaller A/R (area/radius) turbine housing—which increased exhaust velocity but reduced top-end flow. At full throttle, boost climbed past 2.2 atm. The engine detonated. Dr. Vane pointed to a small actuator: the wastegate. It diverted exhaust around the turbine when boost exceeded a setpoint.

Kael derived the energy balance: Total exhaust energy = Energy to turbine + Energy bypassed + Waste heat + Entropy.
