Other features include:
* Surface Engineering Resources. Friction Calculator includes information on coefficient of friction, surface roughness, corrosion rates, wear mechanisms and thread tolerances.
* Friction Engineering Help. Use Friction Calculator to contact General Magnaplate's technical service department to ask for help with your surface enhancement problems.
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.
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.
The motor & pump calculator are flexible tools in which the user can enter any three known values to have the remaining values calculated. Values include: displacement, oil flow, pressure, rotational speed, torque, and motor power. Both mechanical and volumetric efficiency values are used.
Cylinder characteristics can be entered in a number of different ways. Enter hydraulic flow, cylinder velocity, or stroke time and calculate the other two. User can also enter Hydraulic pressure, extend force or retract force and have the other two calculated.
One application for this is to measure the stroke time of a cylinder. By entering this with the bore diameter and stroke length, the system flow is calculated.
Speed - Torque - Power page: Enter any two values have the third calculated. Unit conversions built into the page.
Calculations can be done in either metric or imperial units.
Results can be copied to the clipboard in a text format for use in e-mails, messages, or other documentation.
Basic unit conversions are also available.
With the Hcalc App you can find the pressure loss in pipework using the Hazen Williams formula which is specified in the NFPA 13 and EN 12845 for fire sprinkler systems. You can changed any of the 3 variables, flow, C-factor and the pipes internal diameter and the pressure loss will be calculated.
The second part of the calculator is used to solve the K-factor formula given the flow, K-factor or pressure at a nozzle or fire sprinkler head given the other two factors. By using the slider controls to vary any of the variables (flow, K factor, pressure) you can see the effect they have instantly.
Please remember to press the calculate button after you have made a change!
This version is in metric units only.
It is possible to set multiple phone numbers for message receipt. The application remembers all alarms and augments the last of them. It is possible to set different alarm sounds, quick answer to any number or set silent mode or vibration.
The information contained in this app was taken from a 2,500-page handbook, making it the most comprehensive plumbing system sizing tool available. Instead of lugging around a book or typing information into an Excel spreadsheet, the Plumbing Engineering & Design Tables App provides all of the data you need at your fingertips.
The app’s interactive design tables allow you to choose the appropriate pipe material and other design criteria, and the sizing data appears instantly in either SI or English units. You can quickly and conveniently calculate pipe flow rates and velocities, friction loss, pressure loss, and stack flow rates.
The design tables cover all of the formulas and equations commonly used in plumbing system design projects, including:
· Manning’s equation
· Hazen-Williams formula
· Darcy-Weisbach formula
· Bernoulli equation
· Boyle’s law
· Joukowsky’s formula
· Colebrook formula
· Spitzglass formula
· Hunter’s curve
In the design tables, the available piping material options include:
· Cast iron
· Polyethylene (PE)
· Stainless steel
Data for numerous types of plumbing systems is included, including:
· Domestic hot and cold water distribution systems
· Natural gas and liquefied petroleum gas systems
· Venting systems
· Building drainage systems
· Storm drainage systems
· Vacuum systems
In addition to pipe sizing data, the app also provides:
· Drainage fixture unit (DFU) values for the major model plumbing codes
· Typical resistance coefficients for valves and fittings
· Water supply fixture units (WSFU)
· Surface roughness coefficient (C) values for various types of pipe
· Typical hot water temperatures for plumbing fixtures and equipment
· Building occupant demographic classifications
· Hot water demand per fixture for various types of buildings
· Gallons (liters) of water per hour per fixture
· scfm to acfm conversions
· Basic vacuum pressure measurements
· Conversions from torr to various vacuum pressure units
· IP and SI pressure conversions
· Barometric pressures corresponding to altitude
· Factors for flow rate reduction due to altitude
· Physical and combustion properties of commonly available fuel gases
· Average physical properties of natural gas and propane
· Approximate gas demand for common appliances
· Specific gravity of a variety of gases
· Fractions, decimal equivalents, and millimeter equivalents
· Temperature equivalencies
The full version of the Plumbing Engineering & Design Tables App is available only to members of ASPE. However, numerous features are unlocked for nonmembers to use. We invite you to explore these features and then visit ASPE.org to join and take advantage of all of the career benefits ASPE has to offer.
