# Description

Calculate the design diameter and slope for a section of sewer pipe.

The Manning Equation is used for Calculation of Pipe Diameter and Slope.

Input data are design flow, elevations of ground initial and final.

The app can be used in the SI or US units.

Example: The design flow rate for a section of storm sewer between two manholes is: Qdes = 10 l/s. Find a combination of a standard pipe diameter and pipe slope to use for this section of sewer to meet the criteria of minimun tractive force.

The required minimum tractive force for sanitary sewer in the app is considered as 2 N/m2.

See solution of example in the screenshot.

- Initial ground elevation = 10 m (ground elevation of initial and final manholes is used to calculate the ground slope and check that slope of the pipe is not less than ground).

- Final ground elevation = 9 m

- Length of pipe = 60 m

- Desired flow = 40 liters per seconds

And as a result of the design, after pressing the calculate button, we get the following results:

Slope: 0.02 m / m, equivalent to 2%

Pipe diameter: 0.3 m

height of water in the pipe (depth / diameter): 40%

## Pipe Headloss Calculator Plus

Pipe Headloss Calculator Plus app can be used for estimating frictional head loss in pipes. This app version compared to the free includes fittings and valves calculation and selection of the pipe material.

The total pressure loss in the system results from the combined losses due to friction in length of pipe and friction losses due to valves, fittings, and other components. The first are "major losses" associated with energy loss per length of pipe, and seconds are "minor losses" associated with bends, fittings, valves, etc.

The factors that determine friction losses in pipe are:

The velocity of the water: As velocity increases, pressure losses increase. Velocity is directly related to flow rate.

The size (inside diameter) of the pipe: Smaller pipe causes a greater proportion of the water to be in contact with the pipe, which creates friction. Pipe size also affects velocity. Given a constant flow rate, decreasing pipe size increases the water’s velocity, which increases friction.

The roughness of the inside of the pipe: Pipe inside wall roughness is rated by a C factor, which can be selected depending on material of pipe. The lower the C value, the rougher the inside and the more pressure loss due to friction.

The length of the pipe: The friction losses are cumulative as the water travels through the length of pipe. The greater the distance, the greater the friction losses will be.

The friction losses for, elbows, and tees can also be selected. The friction losses in fittings such as couplings, elbows, tees, valves and other elements play a role. Friction loss from these components must be taken into account when calculating friction losses for each section of pipe.

Calculation of friction factor is based on the Hazen-Williams equation. Local resistances factor K for valves and some fittings (tees, elbows, pipes contraction and enlargement), can be found in app itself.

Example:

Calculate pressure losses in a pumping of 10 l / s. The diameter of the suction and discharge is 100 mm or 4 ". We have the following items on the Suction: 1 foot valve, 1 gate valve , 1 elbow 90, 1 contraction to 3" to entering the pump. In the discharge we have: 1 expansion, 2 elbow 90,

a check valve, 1 gate valve. The total pipe length is 10 meters in diameter of 100 mm. Must be calculated the pressure losses for the given flow.

https://play.google.com/store/apps/details?id=appinventor.ai_garysaunders158.roofer

I can only apologize to all users of the original Roofer App but due to circumstances beyond my capabilities i am only able to create a new version rather than upgrade the old version..THIS NEW VERSION 3 CAN BE DOWNLOADED FROM PLAYSTORE .

Metric Version

Enter the Building Span, Roof pitch and Rafter spacing

and this Reckoner, will return the TRUE LENGTHS of Hip, Valley and Common Rafters to Three decimal points.

It also give you the Jack Rafter diminish and all the Plumb Cuts, Seat Cuts and Jack Rafter Edge Cut angles in degrees for the Roof members.

Newly added Purlin Edge Cut and Purlin Side Cut Angle,

Hip Backing Angle, Hip Edge Angle,Plan Angle and Sheathing Angle.

There is some diagrams on using True lengths on my web site

http://roofersreadyreckoner.co.uk just follow the link lower on the page

Save time,money and less wasted timber when pricing by working out Roof timber lengths using this easy to use Roofing Ready Reckoner as Reviewed in Home Building and Renovating magazine.The review can be read on my website as listed below.

Timber thicknesses for Hip/Valley and Ridge need to be subtracted from the returned true Rafter Lengths and the roof plates must be level, paralleled to each other and square.

Remember this app returns the True Lengths of the rafters..

Disclaimer:

This is a aide to Roofing and a basic understanding of roof framing is necessary, always double check measurements..(measure twice...Cut once).

I have checked the return values rigorously but i cannot check every possible combination of returned values.

As roof projects/building construction are out of my control, i cannot not accept any responsibility regarding materials,workmanships or costs relating to the use of this Roofing Ready Reckoner..always check your measurements.

(measure twice...Cut once).

## Pipefitting 90Deg Intersection

Tired of carrying the Franklin book or 1000 Piping intersections, then this app for 90 degree pipe intersections, or fish mouth is the answer. For Standard Weight pipe sizes ½” thru 24” simply enter the branch line in the first box and the main line in the second box and press calculate.The results are the ordinates (See Fig 20) for 16 points to lay out a 90 degree intersection. This app assumes you’re a journeyman pipefitter (steamfitter) and know how to layout the pipe when the calculated ordinates are given. If not see our webpage http://watersmechanical.com/appsforpipefitting.html for more info. Look for our upcoming app that allows for more pipe sizes and varying lateral degrees.

## Gas Pipe Sizing Calculator

A study carried out by Worcester Bosch Group's technical support team found that the most common cause of a boiler installation problem was from incorrectly sized gas pipes. When fitting a new boiler, often the existing pipes should be replace for larger ones due to the increased output. Smaller pipes will mean the boiler is running at a lower power and can cause an increase in carbon monoxide levels.

The Gas Pipe Sizing Calculator is an extremely easy to use app that will help you to select the right size pipes for installations using copper (up to 108mm), steel (up to 300mm) and PE (up to 315mm) pipes of sections up to 250m (820ft) in length.

To carry out a calculation simply select the gas type, enter the appliance heat input, enter the pipe length, the number of high or low loss fittings (guidance is given in the app), select the type of pipe and then press the 'Calculate' button.

The results will show the total equivalent length, the minimum pipe diameter (metric) that should be used and the pressure drop for that section of pipe.

For multiple appliances each section should be calculated in turn and the kW inputs for the appliances in each section added together for each calculation.

The maximum pressure drop from each appliance to the meter should be no more than 1 mbar for natural gas or 2.5 mbar for butane or propane. Adding all drops together using the minimum pipe diameters may cause this to be exceeded. Where possible, the results will also calculate the drop if the next larger size pipe diameter is selected on a section, this should help to ensure the right sizes are used throughout the whole circuit.

Please note: This app is designed mainly for the UK so supports metric pipe sizes only.

## Water Headloss Calculator

The Hazen–Williams equation is an empirical formula which calculates pressure drop of water in circular pipes caused by friction. It is used in the design of water pipe systems such as fire sprinkler systems, water supply networks, and irrigation systems.

The Hazen–Williams equation has the advantage that the coefficient C is not a function of the Reynolds number, but it has the disadvantage that it is only valid for water.

Input parameters are flow, pipe diameter, lenght of pipe and C is a roughness coefficient, known as William Hazens coefficient, with values between 90 (more rough pipes) and 140 (smooth pipes, ex PVC).

You can select between imperial (U.S. customary units) and metric unit (International System of Units).
