What else can I help you with?
In boiler feed water line whether a non return valve should precede or succeed the delivery valve of feed water pump?
In boiler feed water line the NRV is normally installed between Pump and stop valve if the line is short and an another NRV is installed at boiler entrance and after stop valve if the line is long or pump is 10 to 15 m away from the boiler.
What waters chemical name?
The chemical name for water is di-hydrogen monoxide, in line with the formula H2O.
How do I install a refrigerator water line?
To install a refrigerator water line, first turn off the water supply, locate the nearest cold water pipe, and shut off the water. Next, drill a hole in the cabinet and feed the water line through. Connect the line to the fridge and turn on the water supply to test for leaks.
Is water evbaporating from clothes on a washing line a chemical or phsical change?
Physical. The water changes its state of matter from liquid to gaseous. No chemical reaction (i.e. change) going on there.
What could be causing air to get between submersable pump and pressure tank?
A pinhole leak or a valve on the line not shutting off properly and introducing air into the water line feed.
You have two water heaters hook two the same feed line will both produce hot water Or will one over ride the other?
They will work co-dependently.
What is the use of recirculation line in boiler feed pump?
A recirculation line in a boiler feed pump is used to return part of the pumped water back to the inlet of the pump. This helps to prevent cavitation and maintain a steady flow of water through the pump. Cavitation is a phenomenon that can occur in pumps when the pressure of the water being pumped drops below the vapor pressure of the water. When this happens, bubbles of vapor can form in the pump, which can cause damage to the pump and reduce its efficiency. The recirculation line helps to prevent cavitation by returning part of the water that has been pumped back to the inlet of the pump. This increases the pressure of the water at the inlet, which helps to prevent the formation of vapor bubbles. As a result, the pump can operate more efficiently and reliably. Overall, the use of a recirculation line in a boiler feed pump helps to prevent cavitation and maintain a steady flow of water through the pump. This can improve the performance and reliability of the pump.
Chemical name of water?
Water is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of living things.
What does W with a horizontal line through it indicate?
The letter W with a horizontal line through it indicates a potential hazard of using water to fight a fire involving a particular material that the sign is on. It can be seen on chemical containers with something that reacts dangerously with water, so it is a warning not to use water to attempt to put out a fire involving the chemical.
What diameter is the hard line fuel line in a 1990 maxima for the feed and return?
Found out myself. Feed and return lines are 5/16", vent line is 1/4"
What is the chemical formula of line water?
The chemical formula for lime water is Ca(OH)2(aq) + CO2(g) --> CaCO3(s) + H2O(I). It is an insoluble suspension of calcium carbonate.
How do I feed a water line through the door of a GE side by Side refridgerator gss25jsre?
Not sure about that particular model, but most refrigerators I have seen require taking the freezer door off and running the water line through the bottom hinge of the door.
