A car engine is based on the principle of:
Correct answer: D. None
- A. Bernoulli's equation
- B. Ventura relation
- C. Torricelli's theorem
- D. None
Explanation
The car engine operates based on the principles of thermodynamics and internal combustion, and it is not directly based on Bernoulli's equation, Venturi effect, or Torricelli's theorem. The combustion of fuel and air mixture in the engine cylinders generates power that drives the vehicle. This process involves concepts such as the Otto cycle (for spark-ignition engines) or the Diesel cycle (for compression-ignition engines), which are part of the broader field of thermodynamics.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
