- Q:in engines otto cycle
- Larger valves allow for more volume of fuel/air mixture to be introduced into the combustion chamber. They give an engine more horsepower but can compromise efficiency in the long run. I would rather have smaller intake valves and larger exhaust valves. The advantage to that is better flow of the exhaust. 40 percent of an engines total horsepower and torque comes from exhaust flow. If a person wants more fuel in the chamber all they have to do is change the camshaft to one that has a longer open duration. This will let the desired amount of fuel/air in where you need it.
- Q:Arrange these structures in the order in which blood passes through them-assume the blood is about to leave the right atrium.Put in order:AortaAortic semilunar valveLeft atriumLeft ventricleLungsMitral valvePulmonary arteryPulmonary semilunar valveRight ventricle Superior/inferior vena cavaTissues of the bodyTricuspid valve
- R atrium Tricuspid valve R ventricle Pulmonary semilunar valve Pulmonary artery Lungs Pulmonary veins L atrium Mitral valve (bicuspid valve) L ventricle Aortic semilunar valve Aorta Systemic circulation (tissues of the body) Superior/ Inferior vena cava *The pulmonary veins are the only veins of the body that carry freshly oxygenated blood*
- Q:We have a wall mounted shower head as well as a ceiling mounted shower head. Suddenly the turning valve for the wall mounted head does not work, only the ceiling one does. Is this stripped. Can it be repaired with a marble wall? I have a photo if needed. Thank you ahead of time. Patrick
- The mixing valve is in the handle that turns the water on. You don't need to take down the wall to get at it. The handle come off including any cover plate and the valve is right behind it. Be careful not drop/lose any screws or washers. They are small. The home center sells replacements for certain brands so get that information.
- Q:Hi! I have three brass gate valves surrounding a filter for my well. They are starting to show some signs of leaking. I realize that I might need to replace them... or, there seems to be a couple of places where they could be adjusted. Is this something I should do? Or, if I need to replace them, can you help me put a name to this type of valve so I can have an easier time tracking them down ?
- Creative, While those valves are open, you certainly could try to snug up those smaller brass nuts up on those gate valves just below the handles. That might stop those leaks. If you find that you can't tighten those up anymore, there's nothing else you can do but replace them. Those are gate valves it looks like they are either 1/2 or 3/4. Those valves have female iron pipe (FIP) union-like fittings on each end. There are lots of different types, styles, sizes of gate valves. There are countless ways to replumb what you have there but, if you want to try to make it as simple as possible and just replace those valves, the thing to do would be to shut the water off, disconnect one of those valves, take it to a good plumbing shop and have them spedcial order THAT SAME VALVE! (3 of them) Because you want the exact same thing. (This would be the easiest way). By the way those gate valves that you have are not common ones. They are unusual because they have those union-like fittings at each end. You won't just be able to find those easily. That's why they will more than likley have to be special ordered. Good luck
- Q:My electric water heater relief valve keeps opening 30 min after turning it on.I turned it down to 90F and 30 min later overflow again.when power is off no leak with the water on uld the valve be opening because of over heating?I know it does'nt leak with cold running through it.
- sounds like you may have a bad high limit/thermostat. replace it and it should fix your problem. the valve keeps popping off because of the pressure build up from the bea high limit
- Q:My friend is having 3 valves in her heart replaced with pig valves. Her dr said that putting in human valves raises the risk of her body rejecting them but wouldnt your body also reject a part form different species? And if they only last a few years why use them at all? shes all freaked out about the surgery so I dont want to ask her too many questions
- I'm not a cardiologist, but I suspect that pig heart valves are a lot easier to find and replace (if rejected) that human heart valves. Pigs are geneticaly very close to humans (go figure), till not long ago we were using porcine insulin for diabetics. The heart valve replacement is probably only temporary, meanwhile she might be put on the waiting list of heart transplant recepients. Once a matching human donor is found, she might be have to undergo a complet heart transplant. They dont replace only the human valves, they usualy replace the whole heart.
- Q:I have presta valves on my mountain bike now and only Presta valves can fit through the hole in the rim where the valve goes. If i want to start using Shrader valve tubes, because they are way more common and i can get them at Walmart, is it ok if i bore out the hole in my rim in order to get the Shrader valve to fit
- Yes you can. Many people have done so. Make sure you file the hole after drilling so you will not have any burrs. BTW most tubes come from China so if you want to put in walmart specials or from a reputable bike shop it will do the job. If you want to put presta valves again, then you can buy a grommet that reduces the hole size. If you have an expensive bike and want to keep it original, then I advise not to drill
- Q:I need to replace my egr valve on my 98 Ford Taurus station wagon, and was wondering where is it located and how tough is it to replace?
- And use the engine treatment called Sea Foam. Your throttle body is full of crud from the egr, it gums up the inside of the throttle body and will lead to gummed up egr valve which it has. Best to give a good clean out while you are at it. You can return your egr valve if you have the receipt. With all this info you should be good to go., Hope it helps.
- Q:When my son was three I switched Dr's for him. The new doctor said has he always had a heart murmur I said no that's the first I've heard of it so we went for test. Anyway heart specialist did all tests said my son had Bav a valve disorder in the heart. He said it is very common. However everyone I've ever talked to has never heard of it. My question is does anyone have this what is your story and have you had to have your valve replaced. My son is very healthy active I'm just worried. Any help would be greatly appreciated....thank you!!
- it is a common cause of murmurs in children, and ordinarily they grow out of it, you can relax.
- Q:Alright. The engine is a 7mgte. The clearances for the skims in the intake side is 0.20mm and the exh side is 0.25mm. What happens if i mixed the shims?
- It does make a difference on which shim goes where! Make sure pushrods are in the right place, i'm not sure on that type of engine but some engines have different lengths for pushrods intake could be different length than exhaust! You could also have a bad lifter.
