Calculators Home / Technical Resources / Calculators is commonly accepted to be the most accurate method available for estimating the collapse strength of steel pipe with diameter/thickness ratios common to those used in the construction of water wells This calculation is used to evaluate suitability of use relative to expected loads
26/12/20165 When the sand stops running close the valve and weight the cone with the existing sand Finally calculate the dry density of the soil by given below formula If the test fails compact and perform the test again Calculation The volume of the hole = Mass of sand in hole/Density of used sand Wet density = Mass of wet excavated soil/Volume
The pipe material – different materials expand at different rates So different types of plastic pipe (e g PP PVC PE etc) and different types of metal pipe (e g steel copper iron) will have different coefficients of expansion So it is important to calculate the rate of expansion on each individual type of pipe
How do you calculate the appropriate flow rate (particularly when designing a non-standard biosand filter)? Design maximum hydraulic loading rate = Filtration Rate*Surface Area We recommend that the filtration rate through the sand be less than than 0 4 m 3 /m 2 /hr (or 400 liters per square meter of sand surface area per hour)
This spreadsheet allows the user to calculate the frictional head loss (m) for a given flow rate (LPS) and pipe length (m) for a series of different diameter pipes (in) The user can also find the optimum combination of 100m sections of two pipes of different diameters (in) to "burn off" a
Pipe Flow-Friction Factor Calculations with Excel Harlan H Bengtson PhD P E COURSE CONTENT 1 Introduction Several kinds of pipe flow calculations can be made with the Darcy-Weisbach equation and the Moody friction factor These calculations can be conveniently carried out 06/02/2017How to Calculate Quantities of Cement Sand and Aggregate for Nominal Concrete Mix (1 2 4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability strength setting time and durabilityGet price
This calculator allows you to figure out the head loss for pump selection All you do is enter your specifications and click the update button to calulate total losses for the system Then select a pump based on flowrate and total head loss requirements The pipe manufacturer's recommendations for thrust control shall be followed Example A 12-inch diameter pipe will be installed for an irrigation pipeline system The pipe will be buried under 4 feet of soil and include 90 degree bends The working pressure in the pipe will be 50 pounds per square inchGet price
Thank you for showing interest in buying our book TECHNICAL CALCULATION AND ESTIMATOR'S MANHOURS MANUAL You can buy the electronic v ersion of the Manual containing all the figurest and other relat ed data at theThis Excel spreadsheet helps you calculate erosional velocity in Excel The offshore oil industry often requires the transport of liquid gas and solids in long distance pipelines This causes the pipe surface to erode with the rate of erosion increasing with the flow velocityGet price
Sand for pipe bedding should be used where possible and soil containing sharp angular gravel or cobbles should not be used for bedding of PE pipe The depth of the trench should be suitable to provide the required cover when reinstated PE pipes having a protective outer sheath (multi-layer) may be laid in heterogeneous ground without sand Calculate insulation thickness (minimum value) 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/mKGet price
Gravel Calculator – How much gravel do I need When it comes to a new gravel slate or other aggregate surface understanding what quantities you need is very important Too few aggregates can lead to additional deliveries which can waste time and money To help you estimate how much gravel you will need to cover the required area please use our calculator The calculator is only intended as a rough guide but will help you approximate the likely volume of gravel or slate needed The depth you will need for the aggregate will depend on what size you use and what itGet price

Sand Filtration by means of a sandfilter Depending on the type of water suspended solids concentration oil and grease COD/ BOD iron contents sand filters are sized differently but the basic design data to clarify natural waters are the following Our Sand calculator will help you estimate how many Cubic Yards of Sand you need for your desired coverage area The sand calculator offers 4 Box area fields and 2 Circular area fields for you to calculate multiple areas simultaneously (back yard front yard driveway garden etc )Get price
Adding in the equivalent length of 2 5 pipe-feet per elbow there is a total pipe length of 300 feet plus 250 feet plus 30 feet (for the elbows) or 580 feet Step 3 Calculate the total head loss through the entire filter system 580 feet x 2 psi/100 feet = 11 6 psi plus the 3 psi head loss through the filter for a total dynamic head loss of 14 6 psi Calculation of the Reynolds Number helps to determine if the flow in the pipe is Laminar Flow or Turbulent Flow Pipes that have a smooth wall such as glass copper brass and polyethylene cause less fritional resistance and hence they produce a smaller frictional loss than those pipes with a greater internal roughness such as concrete cast iron and steelGet price
13/04/2015The calculation shows a head loss of 8 46 feet of fluid Next we will determine what happens when the flow rate is changed Since this pipeline was calculated with a flow rate of 400 gpm this example will calculate the head loss for 200 gpm and 800 gpm through the same 100-foot section of 4-inch steel schedule 40 pipe How to Calculate Quantities of Cement Sand and Aggregate for Nominal Concrete Mix (1 2 4)?
