The energy lost through friction as a fluid flows through a pipe. The amount of energy lost is dependent on both the characteristics of the fluid (viscosity, density) and the pipe (roughness, diameter, length) as well as the rate of flow.

When water is flowing through seamless steel pipe that is 36 in in diameterthe rate of discharge is 9500 gpm if the lenght of pipe is 2400 ft the friction loss in the pipe is?
49.334 psi is the pressure loss and to get the friction loss you would need to know the smoothness of the inside of the pipe.
What are the types of pipe losses?
friction loss head loss loss due to sudden enlargement
Difference between shock loss and friction loss?
Friction loss is the loss of energy that occurs in pipe flow due to viscous effects generated by the surface of the pipe. Shock loss is an huge loss that causes an adverse effect on an insurerâ??s assets.
What are the four fundamental rules governing friction loss in hose and pipe?
See frictionlosscalculator.com. They have a good description of friction loss I fire hose.
How do you calculate friction losses in pipelines?
pressure loss and friction loss in a pipe can be reduced by 1) using smooth pipes 2) Using straight pipes, because the more bends a pipe has the more energy it will lose. 3)pumping downhill where possible.
How do you account for friction loss while applying Bernoulli's theorem to the real flow?
Sum the friction terms for each element from which the friction results, including pipe lengths, elbows, flanges, fitting, valves, etc to get a total friction value K-total.When input to the Bernoulli equation the friction loss will be:ef=0.5*Ktotal*V^2where ef is the energy lost to frictionKtotal is sum of all the loss coefficientsV= velocity of fluidThe friction loss coefficient for a length of pipe is:Kpipe= 16*f*L/DwhereKpipe= pipe loss coefficientL= length of pipeD= diameter of pipef=the Darcy friction factor (not to be confused with the similar Fanning friction factor)For turbulent flow the Darcy friction factor can be obtained from a Moody diagram (very simple) or via the Colebrook or Churchill equations (complex). For laminar flow:f= 64/Rewhere Re is the Reynold's number, an indication of turbulence.Turbulent flow occurs at Reynolds numbers greater than about 2000.Be wary of whether the f listed is the Fanning or Darcy friction factor: mechanical engineers use Darcy, chemical engineers typically use Fanning.The Hooper 2K method can be used to calculate pipe loss coefficients.See related links for a calculation form.
What are the factors upon which the friction loss in a pipe depends?
Calculating the friction loss in a pipe can be conducted using one of various equations which include, but are not limited to the Darcy friction factor and the Colebrook equation, and are attributed to the authors of the same. The first thing to consider when determining friction loss is the type of flow in the pipe. There may be laminar flow or turbulent flow which both depend on the velocity of flow through the pipe. The Darcy equation is commonly used for laminar flow only where the Reynolds number is less than 2300, and does not provide accurate values for turbulent flow. The Colebrook equation will provide greater accuracy when flow is turbulent (Reynolds number > 4000) or neither laminar or turbulent (2300 < Reynolds number < 4000). The next item to consider is the type of pipe through which the fluid is flowing. Different types of pipe have different profiles of roughness inside. The friction provided by this roughness will slow down fluid flow. There are constant values attributed to various types of pipe, and can be found in a fluid mechanics text. Next consider the hydraulic diameter. This is the diameter of the pipe and varies depending on the shape of the pipe. Remember, not all piping runs are round. Air is considered a fluid and flows through square or rectangular "pipes". Finally, friction loss will be affected by bends and obstructions in the pipe run. Tables are also available in your fluid mechanics text. Different types of bends and obstructions have different values and must be summed to provide the total loss through the pipe run.
Is a pipe gripped by a stillson wrench an advantage or disadvantage of friction?
is gripping a pipe with a stillson wrench an andvantage or a disadvantage of friction?
Which has less friction on a PVC pipe wood or metal?
PVC pipe has less friction. They are also longer lasting than the others.
What is frictional loss?
The energy lost through friction as a fluid flows through a pipe. The amount of energy lost is dependent on both the characteristics of the fluid (viscosity, density) and the pipe (roughness, diameter, length) as well as the rate of flow.
Why a sound is heard when water is flowing through a pipe?
Water flowing through the pipe creates some friction. That friction creates vibration, vibration = sound.
In the Bernoulli's theorem demonstration how can you improve the accuracy of the results?
we can improve the bernoulli equation by adding the head losses at the final flow state and also we account the major (friction loss and viscus loss) losses and Minor losses (pipe bend , pipe contraction , pipe inlet and outlet, pipe fittings , valves etc)... If we account those losses and added to the head losses then the Bernoulli's equation gives the very accurate value....
