What is work done?
Work done is used as a term to communicate that a predetermined task has been completed OR to specifify a percentage of the task completed by saying that work done is at (f.i.) 70%
What occurs in a steam engine?
Water is heated to produce steam. The steam is used to power the engine. The power from the engine does the work or powers other instruments that do the work.
How does Thermodynamics affect the work of mechanical engineers?
thermodynamics, is essential for mechanical engineers, because the subject is mainly about heat and work in system, and as an engineer that is important, especially when you have to design engines, because that is when you have to determine important factors such as the amount of work that can be done by that engine internally, and the heat it transefered and obtained.
Can work be done on a system if there is no motion?
no
Tell me about engine?
An engine is a motor that converts thermal energy to mechanical work.
The amount of work done by heat engine equals the amount of what?
the amout of work done on the engine
How did work done by the steam engine compare to work done by horses?
the steam engine was quicker and stronger than hoses
How did work done by the steam engine compare to work done by the horse?
steam engine was quicker than horses and stronger than horses
Is work done if you push a car that has run out of gas?
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
How do engine swaps work?
You take one engine out of a car and put another one in. Done.
How did the work by the steam engine compare to work done by horse?
steam engine was quicker than horses and stronger than horses
Is work being done by an automobile operating for several minutes?
No work is being done by the automobile if it is standing still with the engine running since it isn't in motion (not counting any work done by the vibrations transmitted to the air and ground upon which it rests). The engine, on the other hand IS doing work while idling since the parts inside are moving and both having work done on them and, in turn, performing work on other parts.
How much work is done by the heat engine if it takes in 2000J of heat and rejects 1500J of heat?
Work done=Heat in-Heat out 2000-1500=500J
How expensive is it to re-ring an engine?
If you do all the work yourself, it can be done for a couple hundred dollars.
What is the difference between used and re-manufactured engine?
A re-manufactured engine has been re-built while a used engine is just taken out of a car and no work is done to it.
What is the definition of thermal efficiency?
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
A 700 watt gasoline engine and a 300 watt electric motor both do 3 joules of workwhich machine does work faster?
Power, measured in watts, is defined as the rate at which work is done. Therefore, the greater the power of an engine, the faster it does work. Therefore a 700 W engine always does work faster than a 300 W engine.
