Variables Used

Loss of Head Due to Obstruction in Pipe - (Measured in Meter) - Loss of head due to obstruction in pipe refers to a measurement of the energy dissipated in a pipe due to obstruction in the pipe.
Flow Velocity through Pipe - (Measured in Meter per Second) - Flow Velocity through Pipe is the velocity of the flow of any fluid from the pipe.
Cross Sectional Area of Pipe - (Measured in Square Meter) - Cross Sectional Area of Pipe is the area of a two-dimensional shape that is obtained when a pipe is sliced perpendicular to some specified axis at a point.
Coefficient of Contraction in Pipe - Coefficient of contraction in pipe is defined as the ratio between the area of the jet at the vena contracta and the area of the orifice.
Maximum Area of Obstruction - (Measured in Meter) - The Maximum Area of Obstruction is considered as the area occupied by the obstruction particle inside a pipe with liquid flow in it.

STEP 1: Convert Input(s) to Base Unit

Flow Velocity through Pipe: 12.5 Meter per Second --> 12.5 Meter per Second No Conversion Required
Cross Sectional Area of Pipe: 0.0113 Square Meter --> 0.0113 Square Meter No Conversion Required
Coefficient of Contraction in Pipe: 0.6 --> No Conversion Required
Maximum Area of Obstruction: 0.0017 Meter --> 0.0017 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_o = V_f^2/(2*[g])*(A/(C_c*(A-A'))-1)^2 --> 12.5^2/(2*[g])*(0.0113/(0.6*(0.0113-0.0017))-1)^2

Evaluating ... ...

H_o = 7.36960001868575

STEP 3: Convert Result to Output's Unit

7.36960001868575 Meter --> No Conversion Required

FINAL ANSWER

7.36960001868575 ≈ 7.3696 Meter <-- Loss of Head Due to Obstruction in Pipe

What is the effect of having an obstruction in a pipe?

The particle which occupies a certain amount of space or area in a pipe tends to distract the flow velocity of the fluid flowing through the pipe and intern causes energy loss. The head loss due to obstruction is equal to the loss of head due to the expansion from vena-contracta to section 2-2.

What is vena-contracta?

Vena contracta is the point in a fluid stream where the diameter of the stream is the least, and fluid velocity is at its maximum, such as in the case of a stream issuing out of a nozzle. It is a place where the cross-section area is minimum.
