The RL (Reduced Level) of a pipe is its elevation relative to a specified reference point or benchmark, often used in civil engineering and construction projects to establish the vertical position of the pipe. It helps to determine the depth of the pipe underground and ensure proper alignment and grading in the construction process.
14 (: rL
A pipe extended above the roof level is a soil pipe.
Invert Level is the bottom of the pipe, reduced level is the middle of the pipe.
The Invert Level of a pipe is the level taken from the bottom of the inside of the pipe as shown below.INVERT LEVEL OF PIPESection through pipeWater levelInvert levelCrown of pipe
Reduced level (RL) is calculated by determining the elevation of a point relative to a reference datum, typically mean sea level. To find the RL, you can use leveling instruments to measure the height differences between the point and a known benchmark. The formula is RL = Benchmark RL ± Height Difference, where you add or subtract the height difference based on whether you're measuring up or down from the benchmark. This provides the elevation of the point in relation to the reference datum.
you have to go ABOVE the pipe and fall into the pipe ;) since the level is falling bricks just goby the pipe and youre there
you will get a value with (+) or (-) value from (BS-FS) equation.(+) values are put in rise column and (-) values are put in fall column.to calculate RL for each point, add the + value to know RL and subtract the (-) value to know RL.
there are 2 pipe levels:' pipe passage' and 'power up pipe'.they are both found at the lake.
invert level =high level - the reading - the diameter of pipe
RL stands for Reduced Level in terms of elevation. It refers to the height of a point or feature above a chosen reference point, usually a specified datum or benchmark. RL is commonly used in surveying, construction, and engineering to describe vertical measurements.
RL stands for Road Luxery
After you use the return pipe you will warp to the level select area just enter one of the doors and it will bring you to the next level
