- Q: Hello! Can someone please tell me where the water pump is located on this vehicle? Or where I might find the answer to this question?Thanks!
- water pump is located on pass side of the motor right where serpentine belt is
- Q: How can we calculate the maximum pump pressure for chilled water system for a 20 story building
- In addition to what was said earlier you will also need to consider the following. Pipe frictional losses will need to be calculated. If there is a control valve or flow element then need to add 3 to 5 psi. If the chilled water goes thru a piece of equipment there will be a pressure loss across that, (example - cooling coil on an air handling unit, air separator etc) this can range from 3 to 20 psi, the equip vendor should be able to provide this. If your pumps are on the ground floor, you might be able to neglect the pressure due to elevation if the loop remains pressurized by the pump(s). Might be a good idea to have an engineer review this who has sized pumps before.
- Q: does anyone know how a water pump works????????????
- There are a number of different types that work according to different principles. Try an internet search on water pump.
- Q: Is pumping water, the new pump is also this problem, the pump is also working, that is, no water, at night I opened, in the installation of water, second days also make it to noon is not so good
- You pump 1. is fully automatic, 2. have small pressure tank 3., stop valve should be 1., tap water is interrupted, 2. water intake, water out of harmony
- Q: Why does the pump decay when connected in parallel?
- When two pumps are connected in parallel, the flow rate is less than two of the rated flow of the pump. That is because of the loss of the pipeline and the incomplete sealing of the one-way valve (backflow) and the maximum capacity limit of the pipeline. The solution is to increase the diameter of the supervisor, check whether the one-way valve is completely sealed, whether the inlet and outlet pipe is blocked or not, and reasonably reduce the elbow and the valve.
- Q: Is the water lamp in the basement water pump fluorescent or waterproof?
- Not ordinary fluorescent lamp, it is waterproof and explosion-proof fluorescent lamp. And the PE protection line must be added
- Q: I know that the water pump is belt driven, so it would be easy to connect it to my bicycle. What I am wondering is if I can pedal fast enough to make it work. Does anyone know how fast I would need to pedal to operate the pump?
- Idle speed of car at minimum is around 600 RPM.Too fast to pedal.
- Q: The garage told me my water pump was pumping quot;weaklyand needs to be replaced.
- A water pump can start to 'pump weakly' as the blades on the rotor wear out. That will reduce the amount of coolant that is being moved through the system. That causes the temperature to rise overall. Usually that does not happen before the bearing wears out. When that happens you will normally see some coolant dripping out of the weep hole of the pump if the pump is on the outside of the engine.
- Q: first off i should say it is below freezing here....with that said, the water pump pulley is not turnning so.. the fan belt busted which leads me to believe the water pump is frozen...... right?i am currently traveling and have little money to spend on a new water pumpis there any way that anyone may know to dethaw a frozen water pump without damaging it?... i should say, the motor is running great, no cracks or leaks from the cold.
- If the pump is above ground, yes it can freeze. It's more likely that the water line above the pump and well is frozen. Most well houses have heat tape around these lines. Make sure that is plugged in and working.
- 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).
