The amount of thrust created by exhaust pipes, or more accurately, by the engines connected to those pipes, depends on various factors, including the design of the engine, the amount of fuel being burned, and the efficiency of the combustion process.
Thrust is the force that propels an object forward. In the context of engines, it is commonly measured in pounds or Newtons. The thrust produced by an engine is primarily determined by the mass flow rate of the exhaust gases and the velocity at which they are expelled.
In a jet engine, for example, thrust is created by the expulsion of high-velocity exhaust gases at the rear of the engine. The force generated can be calculated using Newton's second law, which states that force is equal to the rate of change of momentum. In the case of a jet engine, the momentum change is caused by the mass of the exhaust gases being expelled at a high velocity.
It's important to note that the specific thrust generated by engines can vary widely depending on their design and intended purpose. For example, a small jet engine on an aircraft will typically generate a few thousand pounds of thrust, while a large commercial jet engine can produce hundreds of thousands of pounds of thrust.
Therefore, to determine the exact amount of thrust created by exhaust pipes, one would need to consider the specific engine and its operating conditions.
