What is the difference between astm a53 astm a120 in thickness of pipe?

The difference in thickness is not by the ASTM grade, but rather by the term "Schedule" - as in Schedule's 10, 40, and 80 - with schedule 10 having the lighest wall thickness, and schedule 80 having the thickest.


What is the basic difference between chute and hopper?

Hopper is a truncated vessels through which the material flows down due to gravity. Chute is usually a pipe / downspout thru which the material (usually from a hopper ) is transported to an end device/storage area.


How many welding rod consume on 36 dia inch pipe?

Depends on the thickness of the pipe wall- there will normally be several layers of weld. A 36 inch pipe may require between 4.8 and 6.6 POUNDS of rod, allowing for a stub of rod that cannot be used. Lincoln Welding has a handy guide to pipeline welding you can read on line.


What is the resonant frequency of an organ pipe related to?

Pipe lengh. a 32' pipe CCCC would produce a ferquency of about 16hz. a 64' pipe CCCCC, 8hz similarly a 16' CCC, 32hz.


What is the difference between static electricity and moving electricity?

Static electricity, such as might build up in your carpet, can best be described as voltage. "moving" electricity is current, which is measured in Amps. I'll skip the math and Ohm's law, and try to give a conceptual answer. If you think of an electric circuit as being a set of water pipes in which the electricity is the water, then voltage is the water pressure and amperage is the rate at which the water is flowing. If the water is flowing through a pipe that does not restrict it, then the amount of water flowing is directly proportional to the water pressure. however, if the pipe resists the movement of the water, then the water flow slows down and the water pressure increases. Conversely, if the pipe exhibits less resistance, then the water pressure drops again and the water flow increases. This analogy gives a basic idea of the difference between static and moving electricity, but it is overly simplified and skips some important concepts. If you've taken physics, you can also think of voltage as being potential energy, current as being kinetic, and resistance as being friction.
