Q:Relationship between power and flow of sewage pump
Severe N= gamma gamma ETA QH/1000 liquid (ox / m3) - N- power efficiency eta (kW/h) - head of M Q- volume flow (M / sec)1, power *0.6= flow * lift *9.82, for the water treatment industry, the flow of cubic meters / hour units,Power = (flow * lift *9.8) / (3600*0.6)3, power = flow * lift *0.0045 (general 50%--90%, large pump higher)
Q:High pressure water pump?
Q:Mazda b2300 keeps Overheating- Already put new Thermostat & Water Pump! What can it be?
Did you put the thermostat in facing the right direction? Did you flush the cooling system? Check the fan to make sure it is working.
Q:took car to mechanic put in timing belt engine coolant and water pump now green fluid leaking what is it?
Almost everytime a mechanic replaces the timing belt, they replace the water pump as well since the timing belt usually drives that pump and it's just practical to do both at once... when they do this, they first drain the coolant (green stuff), then remove timing belt, and water pump (what pushes the coolant around in your engine), they then install the new water pump *and are supposed to also replace the gasket and/or put rtv sealant on the mating surfaces to prevent leaking... I'm going to assume they skipped that step, and the result is coolant (green liquid) leaking out of the pump and making contact with hot surfaces of the engine, which would explain the smoke. Take it back to the shop (if safe to drive, may also want to top off your radiator with water) and demand they fix their messup for free, a good shop will not charge you for their mistakes.
Q:calculus water pumping work problem?
Let the x-axis point upward, with x=0 at ground level. Consider a thin horizontal increment of water, of thickness dx, located at some x (0 ≤ x ≤ 2.5). This water has mass dm given by dm = ρA dx where ρ is the mass density of water (in kg/m³) and A is the area of this increment (A = 36π for all increments here). This increment must be lifted (3-x) meters. The increment of work dW is given by dW = gh dm where g is the acceleration due to gravity and h is the distance that the increment of mass must be lifted (which we've seen is equal to 3-x meters). The total work W is given by 2.5  ∫ g (3-x) 36π ρ dx 0
Q:What is called soft start of water pump?
Close the outlet valve of the pump, open the inlet valve, and can ensure that the water pump "self filling" (the liquid level is higher than the pump inlet pipe under the condition of the water pump start procedure is: to start the motor, to the normal operation of the motor, slowly open the outlet valve, the current gradually increase. But in the unattended operation (valve), and automatically pump, and pipeline diameter and length (in the pipeline water quality will be great), such as the motor start fast, to quickly promote the quality of water (as the train will soon accelerate acceleration), will make the motor starting current is large, causing the motor to trip and the damage of mechanical and electrical. Soft start (soft starter added in the circuit) - that is, slow motor speed, can overcome the above situation.Stop the pump normal order is: close the outlet valve, then stop the motor, such as unmanned operation, the outlet valve is not closed, when the pump stops suddenly, the water inside the tubes (especially vertical pipe), water will quickly turn back, so when the check valve suddenly closed, the fast flowing water suddenly stop by the inertial impact that produces "water hammer" effect and damage of pipeline system, using the "soft stop" should, in the circuit is connected with the soft stop device.
Q:About water pump selection
ZGD1.5KW screw pump, lift 120 meters. Caliber inch. High pressure. Screw type. It can absorb more than 30 meters of water.
Q:my expedition keeps over heating. i put in a new thermostat,water pump allready. help please?
Check the compression,could be a broken ring.
Q:How can I be sure the water pump is the problem before spending $ on repairs. 97 civic overheating.?
You check the water pump by looking at it! Underneath the input shaft of the water-pump is a small weep-hole that leaks coolant if the bearings and seals are shot. If there's no leak in that location absolutely nothing is wrong with the water-pump regardless what you read above. Change the thermostat with a factory OEM unit. Remove the radiator cap when the motor is cold. If the radiator return valve on the bottom is brown and dirty the entire cooling system should be drained, flushed and cleaned. The heater core and radiator cross fins are probably plugged full because of years of not changing the coolant. Is the electric fan working? When the motor starts to overheat, wrap a gloved hand around the top radiator hose. If it's barely warm the thermostat is sticking closed. If it's hot the radiator and entire cooling system needs to be cleaned with Prestone Super Radiator Cleaner.
Q:2000 Chevy Impala with a bad water pump?
It sounds like a water pump or maybe a loose connection. It is probably time for a water pump if it hasn't been replaced yet. Parts will run under $60 and it probably involves an hour of labor. The Impala is a big car, it shouldn't be hard to get to and remove. Taking it to a shop will run under $100-$150 for everything.
