Type of engine used to power space flights?
rocket engines,compared to jet engines
What energy source was used to power steam engines?
water
Why do you have different types of engines?
Because different engines have different advantages. Steam engines can be run from anything that burns, but are big and heavy. 2-stroke (gasoline) engines has great power-to-weight ratio, but tend to use a lot of fuel and create a lot of emissions. 4-stroke Diesel engines tend to run rougher and don't rev as high as gasoline engines but are more fuel efficient and often have more torque.
Why does other air crafts uses 4 engines to fly while others use 2 engines?
It's a question of trade offs and compromises. Two engines are easier to deal with than four engines, you'll only have two throttles, two fuel systems, two oil pressure gauges etc etc. OTOH, to get the same power out of two engines as you would have out of four, each engine has to be doubly powerful, and that's a problem too. It'll be bigger, heavier, might run warmer etc. And if you lose one out of two engines during flight, that's a much bigger problem than losing one engine out of four.
Explain how an acoustic stirling engine works?
Bob told me that the acoustic stirling engines run when you hum to them. No seriously, it's true since Bob told me it was.
Can only engines have power?
No, engines aren't the only things that has power. Anyone or anything can have power if they do work. Power is how quickly work is done and anyone can use power even if it isn't am engine
Explain why gas oil is cracked to produce gasoline?
To produce a higher octane fuel. A fuel that will power high efficiency engines.
What are different types of search engines?
Identify 5 types of search engines and explain the difference between
Why do most very large engines operate on two stroke cycle?
very large is the keyword here. for a very large engines that runs large machines, we need high power engines. two-strike cycle engines produce more power than 4-stroke cycle engines. that's why they are used. as they produce more pollution than 4-strokes, they must be limited to small spaced engines machines or large machines that required very high power.
How would you explain who Dimitria is from Power Rangers?
Dimitria is a mentor to the Power Ranger group. She only spoke in questions to the group.
Can planes fly without the engine running?
With no engines you can't. Engines provide power and thurst as well as cabin pressure. The APU is a back up generator and can provide power when engines are lost.
Where did the term horse power come from?
Horse power is a measure of the power output of engines using the pulling capacity of a draft horse as its base unit. It was originally used to compare the power of steam engines compared to horses and was later extended to included petrol and diesel engines.
Explain what heat engines do and name the process in which they use to burn fuel?
Combustion
How are steam engines diesel engines and electric engines similar and different?
Steam engines and diesel engines are heat engines. An electric motor isn't an engine - it converts and transfers power, but doesn't actually create it.
Is the power of engines measured in hydraulic power or horsepower?
Engine power is measured in horsepower.
Type of engine used to power space flights?
rocket engines,compared to jet engines
How train driven?
Steam power; Diesel engines, Electricity, and a very few gasoline engines.
