Q: does any one know were a water pump is located on a 97 nissan altima? and where can i get a good deal on one?: [with the car jacked up] Follow the rubber pipes coming out of the radiator. You should eventually find a metal device that is connected to your serpentine belt (fan belt). This device is your water pump. The purpose of the pump is to run cool water through the engine to cool it off. It needs to be replaced if it is making noise or if your car heats up too much. hope this helps! :)

Q: I am going to replace the timing belt , tesioner and idler bearing on my 2000 daewoo leganza. I noticed some of the kits have water pumps too. It is likely to break like the timing belt?: I would suggest to replace the car itself.

Q: This only happens while I am running water. I can hear the pressure switch clicking on and off the whole time I am doing dishes, laundry, ... Since it is only when the water is running I believe that means it is not a leak. I changed the check valve and that did not fix the problem. I checked the pressure in the tank and it seemed to be around the 20/40 mark. Any other ideas anyone?Thanks.: It sounds like the bladder in your pressure tank has ruptured.

Q: I have a 2000 Ford Focus with 82k miles on it. The car is leaking coolant intermittently. The radiator was replaced about 3 yrs ago. The car doesn't overheat but when I turn it off I can hear a boiling sound and it smells like something is burning. It's not a strong smell but it's there. The car also idles rough and downright shakes at times. Also, and I know this sounds crazy, when I'm driving it I hear a sort of whooshing noise that sounds like water. Could this be the water pump or something more serious? I'm taking it to the mechanic tomorrow but would like an idea as to what could be wrong.: 2000 Ford Focus Water Pump

Q: I tried using my water line with a pressure tank and pressure switch but without a pressure tank I observed that when he pressure reaches 30 psi the motor pump switches off automatically and when we open the faucets to use water the pressure switch turns on again the motor pump.: A pressure tank acts to mellow out the surges inherent in the action of the pump. Without a pressure tank, the service life of the pump is diminished. Think of using a garden hose at full volume at the end of 50 feet of 1 pipe. That works out to 17 pounds of water moving at a high speed. When flow stops the 17 pounds of water has a tremendous amount of energy that has to go somewhere. It is better if that force goes into an air cushion at the top of pressure tank rather than into the vanes of the pump.

Q: quot;A tank has the shape of an inverted circular cone (point at the bottom) with height 10 feet and radius 4 feet. The tank is full of water. We pump out water (to a pipe at the top of the tank) until the water level is 5 feet from the bottom. The work W required to do this is given byquot;I know how to find it if it's a right circular cylinder, but how do I adjust for the changing area? Also would a and b = 0 and 5? Thanks ahead of time!: calculate the amount of water U start with by computing volume of cone: V = 1/3πr?h {r = 4', h = 10'} V = 0.333π(4)?(10) = 167.55 ft? calculate the amount of water remaining in cone after pumping is done: V = 0.333π(2)?(5) = 20.944 ft? calculate the volume of water pumped: 167.55 - 20.944 = 146.6 ft? 1 ft? of water weighs 62.4 lb, calculate weight of water removed: 146.6(62.4) = 9148 lbs The Center of Mass of the water in the cone (when h = 10') is at 1/4 of 10 ft = 2.5 ft high The Center of Mass of the water in the cone (when h = 5') is at 1/4 of 5 ft = 1.25 ft height The Center of C.of M. change = 1.25 + (2.5 - 1.25)/2 = 1.25+0.625 = 1.875 ft If we consider that the Center of Mass of the water removed was at 1.875 ft, All the water removed was then lifted an average of 10 - 1.875 = 8.125 ft Work done = W = (9148)(8.125) = 74,300 ft-lbs ANS

Q: I'm going to be purchasing a laboratory distillation kit here pretty soon, the kit includes everything I need for the setup but the condenser requires a water pump to circulate cold water around the coils. What kind of pump would you recommend for this purpose?: A small centrifugal pump that has the flowrate designated by the condenser manufacturer. I assume it has a heat exchanger of some type to reject the heat to the air and that would need a designate flow. Anyway, look in any lab supply catalog or web site and they will have many small pumps. You do not need to carefully control the flowrate, so stay away from metering or peristaltic pumps. The pumps may even be made of plastic, that is fine for this application. In my lab, we would just run the water from the tap through the glass condenser and let it drain out to waste. It is wasteful of water, but it sure was much cheaper than buying a pump and heat exchanger.

Q: I am planning to build a koi fish pond, and I know I need a water pump. All I know is that a water pump will circulates water. Does it do anything else? does it act like a filter? does it provide aeration or oxygen to the pond?: It only circulates the water, nothing else. Also, make sure your pond won't be in sunlight the whole day. Sunlight makes algae grow. ~ZTM

Q: I have a slight idea but I would like to see what steps other people have taken. I have a 1992 ford escort that needs a new water pump, what steps have you taken to replace it?: It shouldn't in all probability take that long for a water pump. till they are changing the cam belt on the comparable time which could be greater like it. despite the fact that if ?40 an hour is slightly on the steep component. Get a cost from yet another storage or 2 for the comparable interest and see in case you will discover everywhere greater much less high priced

Q: Work done in water pumping?Water is to be brought from a well 60 meters bellow ground level to a tower 10 meters high, once there the water falls freely on a 5000 liter tank. A submerged pump 10 meters under water level and a two inch diameter pipe is to be used. What is the work done by the pump when 2000 liters have been served to the tank; what is the power of a pump selected to do this work in 20 minutes.: Power_W = (Mass_kg * Gravity_m/s/s * Height_m) / time_s Where: Mass kg is 1kg/l of 2000 liters Gravity is 9.81m/s/s Head is 60m + 10m (height). The suction head is ignored because the pump is submerged. In practice there is some suction head due to intake restrictions like pipes, check valves, strainers. The time is 20 minutes in seconds. The work is the energy used in the time allocated, which is: power * time in seconds, which is watt seconds = joules. Not needed here as it is in the formula above. Power is the rate of doing work. The depth below water is not really relevant except for pipe losses which increase the head slightly. The flow is 2000 liters/20 minutes = 100 l/min. This can be used with the head of 70m to determine the pipe restriction, which amounts to a pressure drop representing extra head added. It will indicate whether the pipe is too small (excessive head added) or whether the pipe is overkill (no head added). You can find on line calculators for this, e.g. search pipe resistance flow on line calculator. I am guessing a 2 inch pipe has little loss at this flow. This is the so called water power. It is the output power of the pump. The pump may only be 50% or so efficient, so the mechanical power delivered by the motor needs to be greater by this ratio. The electrical input power to the motor is greater again to allow for motor efficiency. This might be 60-90%. In practice the efficiency of pump and motor are determined from user manual or specification of the actual devices with the actual loads (head and flow).
