What is the efficiency of an engine that gives off 70 percent thermal enery?

If this, ie 70%, is the total energy loss, it follows that the engine is producing 30% useful energy, so that is its thermodynamic efficiency.

Can you connect three phase enery meter in series with ammeter ct if rating is same?
it's not aloud in a combat zone they also will seize it in the military mail
What is a design E motor?
Design E motors are intended to be more enery efficient. They also have greater starting current than Design B motors. (Design B motors are the more common general-purpose type.) For a brief discussion of Design E motors, see: http://books.google.com/books?id=8NERxTxHGkgC&pg=PT433&lpg=PT433&dq=design+E+motor&source=bl&ots=0hXJzRy7bh&sig=pLXyIkO2U_Kcl6-rzOhT28ofn2Q&hl=en&ei=U684S8ONHYbQngeclqiCCQ&sa=X&oi=book_result&ct=result&resnum=10&ved=0CCQQ6AEwCQ#v=onepage&q=design%20E%20motor&f=false Angelo J Campanella
What is the difference between motor and generator in electrical machine?
A motor converts electrical energy into mechanical energy and a generator converts mechanical energy into electrical energy.Longer answerThe primary difference between a motor and a generator is that one converts electrical energy into mechanical energy (that's the motor) and the other converts mechanical energy into electrical energy (that's the generator).In some cases of direct current (DC) machines, but not alternating current (AC) machines, there is so little difference that a single device (it might be called a motor-generator) can be used as either a motor or a generator.A superb example of this would be the motor-generator that is used in electric vehicles: when the vehicle is accelerated, the batteries supply power to the motor-generator and it acts as a motor, driving the wheels. When the brake is applied, the motor-generator shifts function and the vehicle's inertia is used by the motor-generator to generate electricity and put some energy back into the batteries. This slows the vehicle down. The one device (the motor-generator) is being used in either capacity. The "handle" often applied to electric vehicles with this feature is dynamic braking.They alike because they both have stators and rotors they are different in that the generator is driven by mechanical device that rotates the rotor, the rotor cuts through magnetic force fields and electricity is generated. The motor is driven by an input of electricity into the stator and the rotor is forced to turn by reaction with magnetic force fields.Generator will provides current to load ......... but motor will drawn current............... generator is based on Flemming right hand rule but motor is based on left hand rule.
Difference between electrical and mechanical energy?
Light travels exclusively through space or along optical fibres by the mechanism of electromagnetic propagation. Electrical energy can also do that, in which case it is called microwave radiation or radio waves, but it can also be carried on wires.
What is What is the difference between conductor and inductor?
A conductor is that one which allows the flow of electric current through it. An inductor is also a conductor but in the form of a coil used in varying current circuits. An inductor's role is not to conduct electricity; it is used in alternating current circuits and control it without much power loss. it is based on self induction.
What basic science deals with heat temperature and enery?
Thermal
Does a flashlight use electrical energy or thermal energy?
a flashlight using chemical and gives out electromagentic enery and a little bit of thermal
A dynamite explosion converts chemical energy into?
thermal enery cause it produces heat *and light and sound
Uranium atoms are split enery is released as?
Electromagnetic radiations and kinetic energy; they are transformed in thermal energy.
What if there was only positive energy?
the universe would be unified on the same vibrational frequency creating enery efficiency and unity
A machine has an efficiency of 91 percent if the enery supplied to the machine is 4000 watts what is the amount being used for work?
Turn the percentage into a decimal by dividing by 100: 91% --> .91Work out = (efficiency) * (work in)dividing by a unit of time gives =>Power out = (efficiency) * (power in)P_o = .91 * 4000 Watts = 3640 Watts
When light strikes a black object what enery is it changed to?
When light strikes a black object what energy is it changed to?
Definition of enery effiency ratio?
The energy efficiency ratio is an output reading. This output reading applies to cooling and heating units each hour, with the input being used to measure the system's efficiency.
What is the relationship between thermal enery and heat?
thermal energy is the total energy the body has due to movement of inner molecules, and bonds between them, and heat is the change in thermal energy, when energy goes from body with higher temperature to the one with lower temperature
Why you need to check the cooling water level of emergency compressor on a vessel?
since in compressors due to compresion of gas the thermal enery increases.
What happens to the energy when its released when firewood is burned?
when the wood burns, chemical reactions occur that change chemical potential energy into thermal energy and light enery. Well, the released energy just simply turns into thermal and light enery.
How are thermal energy and temperature alike?
If you increase temperature you increase thermal energy.If you double the amount you have the temperature does not change but the thermal energy does.Temperature and thermal energy are the same since they both use kinetic energy. Temperature uses the thermal energy when the heat measures the average of the kinetic energy. The thermal energy uses the kinetic energy, when it's averged together with the kinetic enery and the others to make the thermal energy.==========================Answer #2:Wow !Temperature is to thermal energy as depth is to water.
