Why is it better to have a round Manhole cover than a square one?
A round manhole cover will not fall through the hole, A square one will.
Why is it eaisier for manhole covers to be round?
1) That way, they can easily be moved, by rolling them. 2) They can't accidentally fall into the manhole.
How much does a manhole weigh?
A manhole weighs nothing...it's a hole. It's the cover that weighs about 100 pounds.
Why manhole is a circle when physics is applied?
So it doesnt fall in, theres no way for a circle to fall into the hole, whereas a square manhole, when tilted at the right angle, could fall in and hurt the workers underneath.
What is a special backdrop that can appear opaque and transparent?
Scrim
What is the minimum spacing between manhole to manhole?
30ft
Will subtracting the invert level of a manhole from the cover level give depth of manhole?
Yes it will give
What is the minimum legal tread depth for a road tire in the UK?
The minimum tyre tread depth in the UK is 1.6mm.
How do you calculate the invert elevation of a manhole?
Invert elevations can usually be found directly on as-built drawings of the sewer facility. The simplest way to calculate an invert elevation of a manhole is to measure the depth of the manhole from the surface to the pipe invert. The invert elevation equals the ground or rim elevation minus this depth. If you do not know the rim elevation or invert elevation, a surveyor must measure the invert and/or rim elevation with reference to a nearby elevation benchmark (see: http://commons.wikimedia.org/wiki/Image:Elevation_Benchmark.jpg). Also, upstream and downstream invert elevations in a manhole typically differ by about 0.1 feet.
What is the Minimum tire tread depth for an motorcycle?
1.6 mm is the minimum
What is the minimum tread depth for tires other than the front tires?
Minimum tread depth for all 4 tires is 2/32"
When did The Manhole happen?
The Manhole happened in 1988.
What is standard depth of earthing?
0.75 meters minimum
When was The Manhole created?
The Manhole was created in 1988.
What is the minimum number of nodes in a binary tree of depth k?
if u assign a 0th level to root of binary tree then,the minimum no. of nodes for depth K is k+1.
What is modulated depth?
In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.
