- Fluid flow velocity in a circular pipe can be calculated with Imperial or American units as. v = 1.274 q / d2. = 0.4085 qgpm / din2 (1). where. v = velocity (ft/s).q = volume flow (ft3/s). d = pipe inside diameter (ft). qgpm = volume flow (US gal./min). = 1.274 q / d2 = 0.4085 qgpm / din2 (1) where v = velocity (ft/s) q = volume flow (ft3/s) d = pipe inside diameter (ft) qgpm = volume flow (US gal./min) din = pipe inside diameter (inches).

- This then sets the outside pipe diameter, the wall thickness (and hence the internal diameter). A list of common standard pipe sizes are given below. A Table of the Most Common Standard Pipe Sizes Nominal Bore 1/2 inch (DN 15 mm), Outside Diameter 21.34 mm Schedule Sch.t should be noted that some intermediate standard pipe sizes are available commercially, such as 5 inch (125 mm), however these are less common. For pipe sizes with a NB of 14 inch (DN 350 mm) and above, the nominal bore is the same as the pipe Outside Diameter (OD).

How to Calculate Sheetrock Keep the walls and ceilings separate. Divide the wall square footage by 32, which is the total square footage of one sheet of 8-foot drywall or the typical wall height of a drywall construction project.For example, if you have 80 square feet, divide that by 32, and you will find that you need 2.5 sheets to cover the wall.nstructions. Measure the length and height of the walls or length and width of the ceilings to be covered. Have a helper hold one end of the tape measure while you check the measurements. Round up all measurements to the nearest foot to ensure enough drywall for the project.

Sample Problem â Insulation thickness calculation for a pipe Determine the minimum insulation thickness required for a pipe carrying steam at 180 0 C. The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 C. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0.04 W/m·K.he purpose of this sample problem is to demonstrate radial heat conduction calculations and practical calculations of insulation thickness also require consideration of convective heat transfer on the outside of insulation wall.

- Multiply the outside diameter in inches by the pressure in psi by 1/2. In the example, this will be 10 inches x 2,000 psi x 1/2 or 10,000. Divide the result of Step 4 by the allowable stress. The result is the minimum wall thickness assuming ideal conditions. In this case, it will be 10,000 divided by 12,900 for a minimum allowed thickness of 0.7752 inches. Multiply the minimum wall thickness assuming ideal conditions by a safety factor, if a safety factor is to be used, or by the manufacturer's tolerance. For example, a manufacturer's tolerance is often given as 12.5 percent or 15.0 percent due to variations in the pipe's strength.

- Draw a rough diagram of the wall and desired path of the pipe. Measure each straight section in the run and mark these lengths on the diagram. Indicate the desired angle of each bend on the drawing. Measure the conduit from the start of the pipe to the first bend and mark with a black marker. Place the pipe in the bending tool and and bend to the desired angle. Most bending tools are manually operated. Insert the pipe in the tool's clamps and pull the handle until it is the desired angle. Double-check that the bend is in the right location by placing the pipe on the wall.

Topics An easy way to determine the thickness of the drywall you have is to seek out an air vent in your wall. Remove the air vent faceplate, which is usually held by a screw. Observe the drywall edge of the vent hole. If cut fairly clean, you should be able to measure the thickness with a ruler.n easy way to determine the thickness of the drywall you have is to seek out an air vent in your wall.

What is a standard wall thickness for a house? Best Answer: An interior wall is usually 4-9/16 thick, if there is plumbing drainage in the will it will be 6-9/16. The exterior wall may vary from 3-1/2 up to 9 depending when the house was built, location of the house, building codes etc. The best way to figure the wall thickness is measure the width of the frame around the door( the door jamb) hope this helps.
