Q:What are the brass instruments with valves?
Trumpet, cornet, tuba, baritone, alto horn, mellophone, mellophonium, Flugelhorn, valve trombone, french horn, Rein horn, Helicon, Wagner Tuba, descant horn, piccolo trumpet, alto trumpet, bass trumpet, some hunting horns (cor chasse), keyed bugles, ophioclide,unihorner, frumpet. and all those drum and bugle corp instruments. I have listed maybe 1/10 of the instruments that have come up over the years with valves.
Q:Can you put a blow off valve/dump valve on a diesel e46 BMW 320d?
Dump Valve Diesel
Q:99 Eclipse Valve Cover?
Usually okorder.com/_... Their pricing is decent and the quality of their work is excellent. They are also on OKorder and have a core/exchange system setup. I'll leave some links for you to check out in the source box
Q:Thermodynamics: pressure change in a valve?
If there is NO change in the density of liquid propane as it passes through the valve, and if the size (area) of the pipe upstream and downstream of the valve is the same, then a) there will be no change in the velocity of propane, hence there will be no kinetic energy change. b) this is a process of throttling, with no change in kinetic energy, hence there is no change in the enthalpy. c) temperature change can be determined using the detailed property table of propane, but if it is an almost-incompressible liquid, then this too, will be negligible. d) dh = T ds + v dp. Since there is no change in h, integrate this along a constant h line from inlet to exit (upstream to downstream) and you will get ds = -(v/T) dp. Since p reduces from inlet to exit, the change in entropy will be positive. This is as expected. If we assume density (=1/v) and temperature (T) to remain constant, then the change in entropy will be s_downstream - s_upstream = (p_upstream - p_downstream) v /T.
Q:where is the bleeder valve?
Remove the radiator cap when cold and run the engine. Have someone rev the engine while the transmission is in park (with the parking brake ON), and you watch in the top of the radiator for bubbles. It may take a few seconds from the time they rev till the bubbles rise to the top.
Q:Trumpet valves making weird sound?
I don't think anyone knows, because there's multiple Bibles. And people interpret it their own way, and re-print it with different scriptures. As far as I'm concerned, there is no such thing as a REAL bible anymore. And any beliefs we have today about it are all false. According to one bible, you will be sent to hell on both counts. According to a modern version, you will be excused for doing your wife, and in another bible, you'll be stonned for asking this question (Knowledge is a sin) Interesting that we are the only intelligent life on earth, supposedly made in God's image, and yet the bible says to stay away from the tree of knowledge. Sorry, I don't buy into that bullcrap.
Q:Replacing Valve Cover Gaskets?
www.okorder.com/
Q:Removing washer hoses from shut-off valves......?
Use a monkey wrench they are probable on pretty good if they are old this should do the trick for you.
Q:valve core?
You can do it yourself very cheaply. All you need to do is go to Walmart or a Auto parts store and get four valve cores and a valve core remover, then go to a gas station the has a air compressor. Remove the valve cores and put the new ones in, you don't have to let all the air out Just put the new valve core in and air the tire back up. I would check the old valve cores before I changed them or have them changed by mixing water and soap together and put in on the top of the valve core, if it bubbles then you need to replace them, if it doesn't bubble someone is just try to scam you.
Q:Will my Hunter SVC VALVE will work with my Lawn Genie Valve?
Your Hunter transformer only provides about half the voltage needed to operate the Lawn Genie solenoid. You might find a weaker spring for the LG solenoid, but the long term fix is to stay consistent. Either use all Lawn Genie, all Hunter, all Rain Bird, etc.
