Is a T8 ballast and T8 bulb more efficient then a T12 ballast and a T8 bulb?
In a T* ballast and T8 bulb more energy efficient then a T12 ballast and a T8 bulb? A:Depends on the CURRENT through the tube. When the Tube is run at 100% of rating, The T12 Takes more CURRENT to give a certain Brightness. Because the surface of the T8 is closer to the ion stream through the tube, it takes less CURRENT to light up the T8 to the same brightness. However, IF you use a T12 in a T8 ballast, you will get LESS CURRENT through the tube, and LESS POWER consumed ALONG with LESS Light.
What is T8 stands for T8 lamps?
Fluorescent tubes are measured in 1/8ths of an inch. A T8 would be 8/8ths or one inch. Likewise a T12 would be 12/8ths or one and a half inches.
Can you use a 4ft 4 lamps T8 ballast to run 4 18in T8 lamps?
You need to match the specification for the T8 lamps in question with the ballast. There are some times form factor issues and other times the specific requirements for the lamp in question.
Can you replace t8 bulb in fixture now using t12 bulb?
Yes a T12 lamp socket will take a T8 tube. The T8 tube will not operate. The T8 ballast is an electronic ballast where as the T12 ballast is a magnetic type. If you are changing over fluorescent fixtures to the smaller T8 lamps then the ballast has to be changed and the end sockets have to be rewired. The schematic on how to do the rewire is on the electronic ballast's label.
How fast are the winds in a T8 typhoon?
There is not such thing as a T8 typhoon. T8 refers tot he TORRO scale, which is used to rate tornadoes in some European countries. T8 is equivalent to a low to mid strength F4 on the Fujita scale with estimated winds of 213-240 mph. However winds on this scale are probably overestimated (ratings are ultimately determined by damage). Based on estimates of the Enhanced Fujita scale a wind estimate in the range of 170-185 mph is probably more accurate.
What is the meaning of main reinforcement bar?
I think the bar along the span is main bar
What is the instrument used to check the reinforcement bar in concrete member?
A cover meter determines the distance from the outside face of the concrete to the depth of the reinforcement bar.
With concrete reinforcement steel what does Y12 bar mean and what does R10 bar mean?
The numbers refer to the different diameters of the rebar used to reinforce the concrete. R specifies round bar. Y or N specify deformed bar. See below. == * Round mild steelreinforcement bar - R6 R10 R12 R16 R20 R24 R28 R33 * Deformed reinforcement bar - N12 N16 N20 N24 N28 N32 N36 * Stock lengths of reinforcement bar - up to 12 metres * S12 Pool Steel - Mild steel bars (not tempcore) that is very easy to bend by hand * Processed reinforcement bars - custom cut and bent to required needs * Dowel Bars - precut, often galvanised round bars used when one slab joins another * Galvanising - Plain Reinforcement Steel bars can also be supplied galvanised *Deformed Bar was previously called Y-Bar eg: Y12, Y16 but through product improvements the tempcore strength was increased (now 500Mpa) and is now denoted as N-Bar as listed above
What is need to provide stirrups bar?

What is the weight of 8mm steel reinforcement bar?

What is the weight of a t16 reinforcement bar?
Weight is 1.579 kg/m
How do you find reinforcement bar running meter weight?
mass=density/volume
A whole bar's rest uses a semibreve rest?
Except in alla breve time, a bar of silence is denoted by a semibreve rest.
What is difference between FE415 FE 500 grade reinforcement steel?
Fe 415 and Fe 500 - both are the types of reinforcement steel. The basic difference is in the tensile strength -denoted by 415 & 500. Fe 500 is economical in comparison with Fe 415.
