- Q:can a person survive with only one heart valve functioning?
- Everyone has correctly identified that there are 4 heart valves. The question of survival is producing a variance in the responses. This may be because you do not define what you mean by 'not functioning'. People may do reasonably well - at least initially - with varying degrees of stenosis and / or regurgitation of more than 1 heart valve. So Yes in a sense if I understand your question correctly a person may survive at least temporarily with only one heart valve functioning perfectly. Please bear in mind that you have not given much information for me to work with in answering your question. If I may be of further assistance please let me know. I wish you the very best of health and happiness and in all things may God bless. JR
- Q:Why can't i start my valve?
- makes no sense try again
- Q:I had to replace the gaskets on my valve cover only to discover that the valve cover had developed a hole due to oxidation. I waited a week for a new valve cover to come in and left the engine exposed. Should I have any issues? I mean its covered but its still outside. Should I pour some oil on the exposed part of the engine?Its been already about a week.
- So long as it is covered you will have no problems. The hood closed, maybe a rag over the hole... I wouldn't give it a second thought.
- Q:When you regulate flow with a valve in a fluid circuit, obviously the flow changes. But mathematically, it changes in function to what? the minimum cross-sectional area? I mean it has to have something to do with some integral of sth (since a valve can change the cross-sectional area of a portion of the tube with length of almost zero and the flow would still change dramatically). I have no idea how to work this through. Can you tell me what changes when you close a valve, which makes the total flow change?Please answer asprecisely as possible, this is for a college essay! thanks in advance!
- A valve reduces the cross-section of the pipe. .
- Q:Ball valves are much more reliable. Also, if you have the gate valve for the main shutoff, is it against code to put a ball valve right after it, so you have a working shutoff when the gate valve fails?
- no as long as the gate valve is there. gate valves are pressure rated and seal better and are made from hardened steel so it will usualy seal when others have a seat [made from brass] that can wear out and leak even ball valves have a ceramic or plastic seal and are made from brass or soft steel
- Q:how to adjust the valves on a 20 horse power briggs and stratton engine on a sears craftman rideing mower model number 917.276824
- you shouldn't have to ! unless you have burnt a valve,
- Q:Is it possible that if you never adjust valves the engine could lose a lot of compression? 1990 Suzuki VX800, 19,000 miles on the clock. No idea if it has ever had the valves adjusted, only got it 3,000 miles and 6 months ago. It is now not running and after a compression test, has 90 psi in the rear and 150 psi in the front cylinder. Don't really have the time yet for a leak down test. Could the exhaust valves be the cause of the low compression? thanks.
- Yes it can lose compression if your valve lash is too tight. This can also cause the valves to burn. Adjust your valves as soon as you can.
- Q:On a Chevrolet truck with a V8...One valve cover has a PVC valve and the other a push-in breather. Would it hurt to put a second PVC valve in so I have one on each side and run 3/8 hose to a T fitting then to the carburator? Good/Bad/Wouldn't hurt?
- No No No, The PVC valve removes a measured amount of crankcase blow by, oil vapor and water to be re-burned in the combustion chambers for emissions standards. The breather in the valve cover is needed to let atmospheric pressure in the crankcase to replace the air the PVC valve and hose has already been removed. I think you've been reading up on dry sump systems. Race engines make more power with a crankcase under vacuum while running.
- Q:1995 Firebird - with digital EGR valve, I think when the engine is at idle, it would be closed, I think.Anyway, this EGR valve has 3 holes that open up whenever.I noticed that the plastic housing on them is melting a little, which probably isn't anything.but I felt around it, and I feel a little air coming out, not from the gasket part, but maybe it has a leak in one of those solnoids somewhere.My cars been idling really ruff, do you think a leak in that would cause it to idle ruff?when I drive, it's fine, runs smooth, but stopping it idles ruff.I just bought that EGR valve 2 years ago, I don't know why it would melt.
- Take the EGR valve off and see if it is internally caked with carbon. Also look at the ports it lines up to on the plenum and see if they are also clogged with carbon. If they are, remove the air intake tube from the throttle body and open the throttle plate. See if the intake plenum is also clogged with carbon. If so, and I think it is, you will need to get yourself a cumbustion chamber cleaning. Those 90s GM cars were bad for this. This will make it idle rough, and also lack as much power as it should have.
- Q:what are the best aorta heart valves. mech. or animal.
- Depending on the valve, the original valve may be able to be repaired. This procedure has only been widely used 8-10 years probably. Originally it was believed that these like animal (pig or cow) would probably only last around 10 years but it is constantly being adapted so longer may be possible. Animal valves do not require blood thinners, although many people I know have ended up on thinners because of other problems. The other advantage is that they are quiet. Mechanical valves, often called metal aren't always truly metal. Older valves were thus a scan using an MRI was not possible. Mine was put in during 1995 and is called metal but does not cause any problem with an MRI and I know others from that time frame also with no problem. I expect it to last my whole lifetime and I never needed any anti-reject meds and few people I know have. I do tick like an old watch especially when I get winded or tired, but over the 13 years I've had it only one person outside of medical professionals examining me have ever noticed. It doesn't keep me awake but I do know some people who notice theirs, but the newer the quieter. I do have to take blood thinners, but for me and most of those I know don't have major problems maintaining a therapeutic level. You have to have a blood test routinely to know but they now have a finger prick machine so it is quick and easy. I only know of one person whose body rejected valves and had to have it removed and animal placed in. From those I know usually children they will do tissue just because a child won't be as careful and watchful of bleeding. Otherwise it is choice based on years wanted from the valve and lifestyle if meds fit and eating habits.
