The efficiency of the street cleaner's engine is calculated by dividing the useful work output by the total heat input. In this case, the useful work output would be the heat input minus the waste heat, or 200000 J - 150000 J = 50000 J. Therefore, efficiency = (50000 J / 200000 J) * 100% = 25%.

What is the efficiency of a street cleaners engine when is that heat input is 200000 Joules and the waste he is 150000 Joules?

The efficiency of the street cleaner's engine is calculated by dividing the useful output (work done) by the input energy. In this case, the useful output is 150000J (work done) and the input energy is 200000J. The efficiency would be 150000J / 200000J = 0.75 or 75%.


What is the efficiency of a street cleaner's engine when the heat input is 200000 joules and the heat waste is 150000 joules?

25 percent


What is the efficiency of a street cleaners engine when the heat input is 200000 joules and the waste is 150000 joules?

If the waste heat is 15 compared to the total heat input of 20 (ignoring the thousands) this means the heat doing useful work is 5, which represents 25 percent of the total input heat, so this is the efficiency. Waste heat in a car is the sum of the engine cooling losses and the exhaust losses, the rest is converted to mechanical energy which is useful. 25%


What is the efficiency of a cars engine when heat input 2000000 joules and waste heat is 150000 joules?

The efficiency of the car's engine can be calculated using the formula: Efficiency = (Useful energy output / Total energy input) * 100%. In this case, the useful energy output is the heat used for work, which is (2000000 - 150000) Joules. Therefore, the efficiency would be ((2000000 - 150000) / 2000000) * 100% = 92.5%.


What is the formula for calculating the efficiency of a heat engine and how is it used in determining the performance of the engine?

The formula for calculating the efficiency of a heat engine is Efficiency (Work output / Heat input) x 100. This formula is used to determine how effectively the engine converts heat into useful work. A higher efficiency value indicates that the engine is more effective at converting heat energy into mechanical work, while a lower efficiency value indicates that more heat energy is wasted. By calculating the efficiency of a heat engine, engineers can assess its performance and make improvements to increase its efficiency.

When your car hit 150000 miles the check engine light came on is this coincidence or is the car programmed to have the engine maintenance at 150000 miles?

its a coincidence that the light came on exactly at 150k. if the check engine light comes on then the computer senses a trouble code that must be checked out and repaired
