CHAPTER 4 DRAINAGE DESIGN

EXAMPLEIf a road culvert is to last 25 years with a 40% chance of failure during the design life, it should be designed for a 49 year peak flow event (i.e., 49 year recurrence interval). When streamflow records are not available, peak discharge can be estimated by the "rational" method or formula and is recommended for use on channels draining less than 80 hectares (200 acres):[price]SMACNA Downspout & Gutter Calulator[hdpe]Calculations are based on level gutter capacity as experimentally determined by the National Institute of Standards and Technology (NIST). Downspout Sizes must not exceed the bottom width of the gutter. To limit the effects of thermal expansion in gutters, 50 ft. (15 m) is a practical maximum gutter length to be served by a downspout.[price]How to Calculate Gutter and Downspout Capacity Hunker[hdpe]Gather some basic weather information to calculate the proper size for gutters and downspouts for a house. The total rainfall and how rapidly it falls will affect the runoff from the roof. An inch of rain is not much, but it if falls in half an hour it could flood a gutter. Total roof area also affects runoff.

A Fixture Unit is not a flow rate unit but a design factor based on the rate

Downpipe and Eaves gutter Calculator

Down Pipe size not listed A few of the uncommon pipe sizes are not listed, eg sizes smaller than 90mm, 125mm dia etc. However any size can be calculated by entering the diameter into the "Any circular DP dia" box. Rectangular DownpipesEnter your chosen dimensions in the box given. It doesn't matter which is side1 or side2.[price]5 Steps to Calculate Total Roof Drains Needed[hdpe]Leader / Pipe Size (in.)

HDPE pipes calculations are done without heat treatment while production. For this reason, HDPE pipe weight & thicknesses table should be taken into consideration when preparing tolerance values.[price]Standard Pipe Schedules and Sizes Chart Table Data [hdpe]Standard Pipe Schedules and Sizes Chart Data for ANSI / ASME B36.10M and API 5L.

How can calculate AHU or FCU condensate drain Pipe

Then based on the standards from ASHRAE /ISHRAE or from Buildings Codes one can easily select the drain pipe sizes per flow requirements as calculated above. To find the correct U leg lengthsas a rule the difference in the heights of U legs should be mm larger than the static pressure of the AHU blower.[price]How to calculate a fire sprinkler system[hdpe]Q = flow through the pipe in L/min C = friction loss coefficient d = internal diameter of the pipe in mm. We know that the flow rate from the sprinkler at node [130] is 76.50 L/min and this will be the flow rate in the first pipe between nodes [130] [120]. As the pipe has an internal diameter of 27.30 mm and has a C value of 120 this will give us:[price]Standard Pipe Schedules and Sizes Chart Table Data [hdpe]Standard Pipe Schedules and Sizes Chart Data for ANSI / ASME B36.10M and API 5L.
