Open ended experiment: Head loss due to friction and pipe fitting in round smooth pipe

Introduction
To verify that Darcy – Weisbach equation can be used to predict the head loss due to friction with of water through a smooth bore pipe.

Apparatus
HF 135 Piping Loss Test Set.

Summary of theory
For water flowing through a circular pipe, the head loss due to the friction can be calculated using Darcy – Weisbach equation.

H =

Where:
L = length of pipe between tapping (m) = 1.25m for all pipe. d = internal diameter of pipe (m). v = mean velocity of water through the pipe (m/s). g = 9.81 m/. f = pipe friction coefficient.

Having established the value of Reynold number for the flow in the pipe, the value of f can be determine the Moody diagram.

Where: Ns/. p = density = 999 kg/ .
Procedure
1) The flow control valve and the inlet isolating valve were to be fully opened. The outlet flow control valve was opened to release trapped air.
2) Isolating valve for test pipe 1 is to be opened.
3) Two manometer tubes should be inserted into the tapping points. The tapping valve is then turned opened. Air should be released by opening the air vent of the manometer.
4) Turn the pump on.
5) The drain should then be closed and use a stopwatch to time the amount of water flowing through the pipe
6) Note the reading of the manometer.
7) Once that’s done, the drain should be opened and the water should be let out slowly.
8) The flow of water should be changed by regulating the outlet flow control valve.
9) Once again, measure the flow of water and the manometer reading.
10) At least 6 readings should be obtained per experiment.
11) Turn off the pump, shut the isolating valve and the tapping valve for test pipe 1
12) The manometer is then inserted into the tapping points for test pipe 2 and open both the tapping and isolating valve.
13) Run the pump and all the relevant readings should be taken
14) The procedures were repeated for test pipe 3.

1 ME313L Fluid Mechanic Lab Manual (DRAFT) diameter pipe 524 mm long. Pressure taps are located at both ends of the pipe. The pressure drop is measured by a water manometer attached to each pressure tap. The water flow rate is controlled by a needle valve. The water is then collected in a calibrated beaker and timed for flow rate and the returned to the hydraulics bench. B. Turbulent Flow The equipment for turbulent flow measurements is the same as that for laminar flow measurements with two exceptions. 1) The flow from the hydraulics bench goes directly to the pipe friction test bench though a ball valve C and the header tank (and valves A and B) is bypassed . 2) The pressure drop across the test pipe is measured by a mercury Utube manometer. The turbulent flow water loop is shown below. Procedure: A. Laminar Flow 1) Ensure that the valve on the hydraulics bench is closed and the pump is turned off. 2) Open ball valves A and B and close ball valve C.
