Q: Pump head is too high what's the impact?: After the determination of the pump type, such as the actual pump lift is too high, it will not only result in lower efficiency of the pump, and will seriously affect the actual flow of the pump to Q decline. On the contrary, if the pump head selected too high, but the actual operation of the lift is too low, is also affecting the pump efficiency and decrease caused by actual operation when the flow is too large, it is likely to increase the pump power beyond the rated current of the motor and the heating.

Q: 7.63Determine the isentropic efficency of a water pump when water enters as a saturated liquid at 96.5 kPa and exits at 5 MPa and 106 degrees C.Thanks: For the best answers, search on this site https://shorturl.im/ayhr9 1] INefficiency is associated with an increase in entropy, so the term 'isentropic efficiency' bothers me 2] Find the temp corresponding to a saturation pressure of 96.5 kPa [hint: something less than 100C]. 3] Look at the entropies in and out

Q: Weap seal is starting to leak and getting some noise from the water pump. These cars are not as easy as a 1969 Camaro to change the water pump. Can you please give me some guidance? Thx in advance.: 2001 Chrysler 300

Q: The flow of the pump will be reduced, the speed will change, the power of the motor will change?: Water pump flow rate, speed will not change, the power of the motor will change in general.Different types of pumps have different flow power curves. Only the most common centrifugal pump is used as an example to illustrate the relationship between the flow rate and other pump parameters. The typical centrifugal pump flow power curve is shown in the P-qv curve (red line) shown below.Turn left and turn right |According to the flow power curve, it can be seen that with the increase of the flow rate, the power increases linearly, and the power decreases linearly with the decrease of flow rate.In fact, the pump shaft power P= P gQH/ (1000 K), including H: head, unit m, Q: flow unit m3/s, ETA: for the efficiency of the pump, general 0.7-0.85, P: shaft power, unit kW, K: matching coefficient, small power is 1.25, P: work is like a water medium density.Therefore, for a specified pump, the power is proportional to the flow theoretically. In fact, as the flow rate changes, the efficiency of the pump changes, so it can only be close to the positive proportion.Running water pump speed generally depends only on the pump, power (motor, diesel, etc.) speed, the flow of water generally can not affect its speed. But in the design of pumps, the flow is related to the speed, and other design parameters remain unchanged, the pump speed is high, the pump flow.

Q: replaced one themostat, disconected lower unit twice look at the water pump everything looks fine but when lower unit was reconnected water pump would not work. not sure if asembled it wrong or forgot to d somthing. can someone help.: check the water tube conection to make sure it is lined up and check to make sure the key is not sheered or missing from the water pump impeller

Q: Multi storey residential buildings also need to set up pressurized water pump room, direct water supply can not be?: Some water pressure is not enough, and since you are multi-storey, you need to add booster pump downstairs

Q: Hi, my water pump isn't working in my rover 400i V reg 99 model......does anyone know where under my bonet this is located and whether it's easy done at home?: water pumps are never an easy fix. most the time you have to take the fan off, and the radiator as well so a person has room to work. MOST water pumps are in front of the motor, towards the bottom. If you follow your radiator hoses you will find it.

Q: The role of water replenishing pump in circulating system: There are three ways of constant pressure in water system. 1, the expansion tank constant pressure, this method applies to small and medium water systems, low cost. 2 water pump constant pressure, the role is when the system because the water shortage during the operation, resulting in insufficient pressure, the water supply system can play the role of water pressure. 3 pressure tank fixed pressure, pressure tank fixed pressure at the same time, also need replenishment pump water, the individual feel that the first two kinds of economic reality

Q: I have a four cylinder ranger with manual transmission. The top pulley was making a squeaking sound the other day and stopping and going. The car stalled out so I had to give it gas for about a minute, and this has happened several more times in the past week. And the car is making a somewhat loud rumbling/clanking noise, which I'm guessing is the bearings on the water pump. So my question is how much will a new water pump cost, I've seen prices quoted on here from $150-$700. Also, it was in the mechanic the other week and I asked him to check the ac compressor and he said it was fine.Thanks: are you sure it's not the belt tensioner rangers had a huge problem with them.I just replaced mine cuz it chewed the belt up was making the most horrible sqealing for a long time

Q: I would like a website that has pictures but any info would be helpful...: Even if you put the auxiliary water pump on its still going to leak. The water will still circulate through it. All you need to do is buy a gasket and some silicone, spend a total of $50 and fix it.
