Q:Long story short, have a 2001 acura tl had a rough idle/ no start issue. figured out by disconnecting vaccuum from the throttle body the idle was fine with the TB pulling air through the disconnected hose port. The hose i disconnected leads to the purge valve solenoid. I removed it and it is closed (no air flow), restarted car with hose disconnected and solenoid still harnessed in (still closed). Just need more info on the function of this thing and what it should be doing.. Can i bench test it with +12V and ground on the two pins? Thanks in advance.: When okorder

Q:Glob Valve or Gate Valve: Gate valves are more commonly used on ships, however any type of valve will work as there really isn't any pressure acting on the valve. Butterfly valves are used in many newer vessels as they are cheaper to purchase. I don't recall ever seeing a ball valve used on a sea chest, nor a globe valve?

Q:Liquid propane leaving the reflux pump of a distillation column flows through a 3.5 in ID pipe at a flowrate of 90 lbm/s. There is a flowrate control valve in this line, and it is set such that the pressure drop across the valve (delta)P=15 lbf/in^2. Upstream of the valve , the pressure P1=18 bar and the temperature T1=310 K. Assume there is negligible heat transfer with the surroundings and that the density of the liquid does not change significantly.a) What is the kinetic energy change across the valve?b) What is the enthalpy change across the valve?c) What is the temperature change across the valve?d) What is the entropy change across the 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:Why can't i start my valve?: what kind of valve are you talking about? A Valvo?? LOL...No really, what kind of valve? Valves do not start, once the engine is fired up then the valve becomes a part of the engines 4 cycle system of opening and closing to allow fuel and air to enter inside the combustion chamber and ignite the fuel to keep the engine running. good luck..

Q:I am trying to repalce the water turnoof valve under my sink but the valve just keeps turning and no progress is made to get it off so I can put on a new one. I am turning it clockwise but it just keeps turning. Can someone please tell me how to get this off? I do not want to have to call a plumber for something that I might be able to fix myself.Thanks.Sandy: basically component to the diverter valve is broken, besides the undeniable fact that, it extremely is terrific to replace to total diverter stem. If their are 3 handles, you are able to do away with the middle one devoid of turning the water off. Then convey total stem with you to the ironmongery shop. There are quite some video clips on youtube and different ironmongery shop factors of interest in case you like help. good success.

Q:I am looking at buying a 2001 Pontiac Bonneville and the guy said the car's check engine light says it had a problem with the EGR valve and so he bipassed it somehow. He said a EGR valve isn't needed. Is this valve very important or needed? What does it do? Thanks: You need an EGR (exhaust gas recirculation) valve. You can bypass it temporarily but your gas mileage will suffer and the check engine light will remain lit. They are usually located near or under the intake assembly are are easy to change. You will need to reverse the bypass that he did so ask him how he did it.

Q:I just replaced my fill valve and all the other toilet components with a universal korky brand kit about 2 months ago and the fill valve is making a hissing sound once the water fills up in the tank. There are also air bubbles that come from the vents on top of the fill valve. I went to the Korky web site and they say that it is a faulty flapper but i checked to see if there is a leak by dropping one of those testers into the tank and there appears to be no leak. Any suggestions?: Korky Toilet Fill Valve

Q:Grade seven, my teacher's a pain. She didn't even explain the 'sets', we just know what valves are in general. So.. which set of valves closes when the ventricles contract? Relax? Thank you so much!***10 POINTS***: There are two types of valves in the heart: the atrio-ventricular (AV) valves and the semi-lunar valves. There are two AV valves: the tricuspid between the right atrium and the right ventricle, and the mitral (also called bicuspid) between the left atrium and the left ventricle. There are also two semi-lunar valves: the pulmonic semi-lunar, between the right ventricle and the pulmonary trunk (artery) and the aortic semi-lunar, between the left ventricle and the aorta. During diastole (the relaxation phase), the AV valves are open and the semi-lunar valves are closed, so the ventricles can fill with blood. During systole (the contraction phase), the AV valves close and the semi-lunar valves open so the blood can be pumped around the body.

Q:I have a 1993 Jeep Grand Cherokee 5.2L V8 I posted a question on here before and many thanks, What I had was a bent rod well I took off the head and removed all the valve springs and found that where the bent rod was the valve stems are bent too. What else do I need to do? or can I clean the head up make sure no valve holes are bent, replace the rods and valves and be good to go. I want my jeep running again!!! Thanks: Valve stems don't usually bend unless the valve hits a piston. I am assuming the rod that was bent was a push rod. The 5.2 engine is not an interference engine, so a cam timing problem would not cause the piston to hit the valve. I suppose that if you way over reved the engine a lifter could have pumped up and at a very high RPM the valves may have floated causing one or more to strike a piston. Push rods do bend for a variety of reasons, but to have a bent push rod AND a bent valve stem I would need more information to give you even an educated guess. You have the head off so look at the top of the piston and see if it looks like it was hit by the valves. Take the head to a machinist and have him check it for cracks and damaged guides. Have him check the valve spring tension also.
