Q:Water pump maximum flow and standard flow?
The parameter standard of the pump factory is determined by its efficiency, that is, the efficiency of the pump is highest at that point. All parameters have two curves, that is, a flow curve and an efficiency curve. You can according to your standard flow, see how much the efficiency of the point, the maximum flow efficiency is how much will know.
Q:My fish tank pump is deep enough, it doesn't bubble up. Without oxygen supply, but it can filter. Does it damage the pump itself?
The easiest way is to pump a bottle of mineral water under the pump. It's too long to cut off some of it.Bottle to the end, the pump can beat oxygen on the line. A hole is under the bottle.
Q:Water pump leaking but not dripping anything. how important?
yea the water pump circulates coolant through the entire cooling system. if you wait until it fails completely, your engine will overheat. i would get it done as soon as possible to prevent further engine damage if it does happen to fail.
Q:When does my water pump need replaced? ?
What kind of car? That info would help. Well, usually on most import cars and some domestic, the timing belt runs the water pump. If this is the case, then yes i would be replacing the water pump with the timing belt because if you don't then when the pump leaks you'll end up paying almost the same money again for water pump job.
Q:Water pump housing is NOT available at any parts store.?
Not sure what you mean by housing. Nobody is going to have just the housing. The entire Water Pump is available from Autozone, from $22 - $63 depending on type and warranty. The severe duty and new pumps are special order/available to ship. The standard reman is available in store, at my local store at least. Same pump as the 5.2L and 5.9L V8's. Can't be that hard to find. This is assuming of course, you have the 3.9L?
Q:Honda Accord 1996, new water pump/timing belt/oil change, smoke coming out from under the car and heats up?
Almost every time i have seen this in my 35 years of exp.its turned out to be a cracked block or head.
Q:WATER PUMP REPLACEMENT?
It depends on the make of the car. Some Hondas and Meesoshitties require replacement of the timing belt whenever it is removed due to stress factors and crap. So it is always a good idea to go ahead and do since on a lot of front wheel drive cars you will have everything off in front of the timing belt anyways. So might as well do it right? Better that than end up on the freeway with a snapped timing belt. Not fun.
Q:What size water pump should I get?
A 3/4 horse pump usually has a one inch suction and 3/4 inch outlet and is more than enough to water one acre. Remember, you don't have to water every day or even cover the entire acre all in one day. The industrial/agricultural pump mentioned before (4 inch? 6 inch? Or more?) is intended for use on dozens of acres per day.
Q:Water is pumped through a pipe of diameter 13.0 cm from the Colorado River up to Grand Canyon Village,?
a) Pressure is the weight of a 1 meter square column of water. The height of the pipe is 2311-564 = 1747 m volume is 1747 m³ density of water is density of water at 20C = 0.998 g/cm³ = 998 kg/m³ mass of water is 1747 m³ x 998 kg/m³ = 1744000 kg weight of water is 1744000 x 9.8 = 17090000 N Pressure is 17090000 N/m² or 17.09 MP b) Cross sectional are of pipe is A = πr² A = π(.065)² = 0.0133 m² one meter of pipe has a volume of .0133 m³ 4300 m³ are pumped per day The water in that one meter of pipe has to be changed 4300 / 0133 = 324000 times per day to handle the flow That is 324000 / (24*3600) times per second or 3.75 times per second. Since the section of pipe is is 1 meter, that is 3.75 meters per second.
Q:How much to replace a water pump on 2006 Mitsubishi Raider?
Have you asked the dealer to send you the part at least? Call Mitsubishi and ask it that would be possible, you never know. You could send in the old pump and possibly get compensation. Keep your bills. Discuss it with them. Your dealer should provide you with the area Mitsubishi representatives contact information. The prices for those can be expensive. Ask the dealer, service dept, for the labour, how many hrs. to change the pump. They should tell you. Also for the cost of the pump. Add the two together and you have your ans. Join CAA, or AAA, get a gold card, wait two days for the card's towing to take effect, then have it towed in on the card. Done all the time. Or if you have a relative with a Gold card they can have it towed in as long as they are with the car with their card when the tow truck comes.
