What should intake and output be?

What is normal fluid intake and output?

What do you think would be the normal fluid intake and output if we took a 30 minute ride?

(it's only an easy grade mountain trail).

Also, I asked my friend who is used to working out, what she did for warm ups, she does 5-10 pushups and 1-3 sets of 50 jumping jacks in the morning when she wakes up. Also in the morning she tries to finish with a 5-7 pushups (she claims that she works out for her entire day and then she rests at the end and has only done this workout 2x a week for the past 2 months, last time she did the workout was 2 weeks ago).

When I asked how much she usually drinks while doing this workout she said that she drinks 1-2 quarts before her workout starts and in between sets, it is a low volume of water (maybe 1/3 liter), she says that this volume of water is more than enough for her. She says that when she finishes she doesn't feel dehydrated and this is because she drinks "enough".

My question is, if the above are the normal volumes of fluid intake and output during a workout, what would be the normal volumes? What volume would be appropriate in her case? Should we expect more from her? Should we expect more from our personal trainer than this? We all have different body composition's and metabolisms. Most of the times with newbies, they tend to overestimate their capabilities. In your situation, you are already dehydrated when you come off the water. That is why your muscles feel like they've been hit with a baseball bat.

Are intake and output supposed to be equal?

The intake air temperature in the air intake tunnel is usually 40C and the outlet air from the muffler is probably 20C.

I have a guess that the actual power output will be higher than what I am using. How is the actual intake and output supposed to be divided between each other (or what is a reasonable factor)?
I am interested in comparing an 80-130mm engine so 1kW per horsepower would be great!1-0.7 times (p) div (t) approx 0.

That ratio for gasoline engines increases (1 kW/hp or 4 W/hp for diesel, and up to ~ 6 W/hp for diesels with forced induction) at higher engine speeds and lower revolutions, reducing that ratio as engine speed changes. In all cases, we're still talking a very large fraction of a horse power that does work over a wide speed range, but this is just an order of magnitude estimate, not a definitive number.

In most applications where an intake and exhaust heat exchanger exists, the design goal is to ensure that the exhaust is cooler than the intake, which is done either by designing the exhaust such that it has a higher rate of cooling, or it's done through some other process.

What should intake and output be?

When the intake is not good, the output will be bad.

When the intake is good, the output will be good. Why are we doing this?

If I have a car, and I make the engine run, and the engine will run well. If I have the same car and I make the engine stop, then the engine will not run. So, what is the engine? The intake or the output?

Intake is what you take in. Output is what you produce.

Your engine is the intake. The fuel you put in is the fuel.

Intake is also called input, because you put it in. The reason you want to control intake and output is so you can run or stop your engine. If you had an engine that worked only on the fuel, it would be useless.
