What is nominal cover to concrete?
it is the clear cover for stirrups. effective cover of the reinforcement = nominal cover+ diameter of stirrups+half diameter of main bars
What is inside diameter of 8 clay pipe?
Diameter of clay sewer pipe are dependent on the manufacturer and the nominal diameter of the pipe (generally ranging from 4" to 30"). For one manufacturer's specifications see: http://www.loganclaypipe.com/pp_pipespecsdata.html
Pressure 14.5psi flow will be 700gallon per day how will calculate the pipe diameter?
I want to know based on flow and pressure how to calculate diameter of the pipe
What is the weight of steel bars per foot?
For Mild Steel Bars: Diameter (in inches): 1/4" Weight per foot: 0.167 lb/ft Diameter (in inches): 3/8" Weight per foot: 0.376 lb/ft Diameter (in inches): 1/2" Weight per foot: 0.668 lb/ft Diameter (in inches): 5/8" Weight per foot: 1.043 lb/ft Diameter (in inches): 3/4" Weight per foot: 1.502 lb/ft Diameter (in inches): 1" Weight per foot: 2.670 lb/ft For High-Strength Deformed (HSD) Steel Bars (commonly used in construction): Diameter (in millimeters): 8 mm Weight per meter: 0.395 kg/m Diameter (in millimeters): 10 mm Weight per meter: 0.617 kg/m Diameter (in millimeters): 12 mm Weight per meter: 0.888 kg/m Diameter (in millimeters): 16 mm Weight per meter: 1.579 kg/m Diameter (in millimeters): 20 mm Weight per meter: 2.467 kg/m Diameter (in millimeters): 25 mm Weight per meter: 3.853 kg/m
What is Development length for steel bars?
Lap length is the length overlap of bars tied to extend the reinforcement length.. Lap length about 50 times the diameter of the bar is considered safe. Laps of neighboring bar lengths should be staggered and should not be provided at one level/line. At one cross section, a maximum of 50% bars should be lapped.In case, required lap length is not available at junction because of space and other constraints, bars can be joined with couplers or welded (with correct choice of method of welding).
What diameter of stirrup is used in column reinforcement?
Usualy 8mm of stirrups will be used
What is nominal cover to concrete?
it is the clear cover for stirrups. effective cover of the reinforcement = nominal cover+ diameter of stirrups+half diameter of main bars
What is lap length in reinforcement?
40 times diameter
How do you calculate the crank length of column reinforcement?
diameter multiply by 20 times example: 8mm*20=160mm
How do you calculate inch diameter for reinforcement pad in pipe?
Reinforcing pads mirror the pipe that they are being welded to in size, thickness, and material. To measure the diameter of the pad, measure the pipe at a cross section.
Why do you need to lap reinforcement?
Lap reinforcement is needed because if lap is not given in a steel structure,that portion will be filled only with mass concrete and it will not attain the expected strength,so inorder to prevent that we can provide a lap rod whose length is 50D i.e 50 times the diameter of the rod.

What is the actual diameter of Pocket watch size 8?
American pocket watches classified as size 8 are 36.4 mm in diameter.
What is confining reinforcement?
Confining reinforcement refers to reinforcement that is applied in such a way that it "confines" the concrete within it to provide increased strength and deflection capabilities. Confining reinforcement is used in both beam and column designs. In columns, spiral or helix reinforcement is implemented through the column, spiraling from top to bottom, with vertical longitudinal bars running through the inside of the helix. This prevents the concrete's diameter becoming larger under the applied load leading to failure. In correct terms it prevents the poisson's effect within the column. In beams the confining reinforcement is generally place within the compressive region of the beam. This can be utilised to increase the yield deflection of the beam as well as the yield and ultimate loads. This is a good option for increasing the ductility of high strength concrete beams which would normally fail in a brittle manner.
What is the square footage of a 9 sided building with a diameter of 28 feet?
Making the rather dubious assumption that the building is in the form of a regular nonagon (why should it be?), the area is 566.9 sq feet.
Is the Empire State Building bigger than Uranus?
