The results in Figure A2 show that the loss in Q due to the gate valve was the lowest 5 m and that due to exit loss was the highest 25 m at Q of 40 m3h. Fig 1 illustrates this in a simple case.

EGL is the ratio of head loss to pipe length as indicated below for a gradual expansion on a downward slope. An introduction to fluid mechanics made. Any change in static pressure is due only to friction loss.

Nabeel ahmed khan submitted to. This energy drop is dependent on the wall shear stress τ between the fluid and pipe surface. 51 Laboratory setup for low flow rate Water Manometer For lower flow rate experiment which is for first 12 readings bench value is opened and water is trans ferred.

The frictional resistance to which fluid is subjected as it flows along a pipe results in a continuous loss of energy or total head of the fluid. LAB Report Experiment 3 HEAD LOSS IN PIP. A gate valve provides friction to the flow of the fluid in a pipe.

Page 2 Introduction This experiment was conducted to measure the head loss in the pipe due to friction between the fluid and the wall of the pipe. With the any circuits of flow to chose from. F Friction factor.

Pipe line introduces extra friction in addition to normal friction due to the walls of the pipe. To achieve this objective we used a hydraulic bench with a hydraulic motor test-pipe with a constant diameter. Different flow rates were introduced along with a different diameters and roughness of the pipes.

Therefore we measured the friction factor of the pipes using our measurements. Looking for frictional losses in piping network due to report lab is called as circles and. Open the bench valve and set the flow at the maximum flow in Part A ie 17 litermin.

Energy Loss in Pipes. Open the ¾ old pipes capillary tubes upstream and downstream so that the head loss could be monitored. The total energy loss in a pipe system is the sum of the major and minor losses.

Fluid Friction Lab Report. Experimental procedure 1. The head loss due to friction may be.

Unlike the major head loss the minor head loss does not have a friction factor that is dependent on the Reynolds number. Friction loss is the loss of energy or head that occurs in pipe flow due to viscous effects generated by the surface of the pipe. Turbulent flow 2Laminar flow 3 Where.

The water tank was emptied of water and the refilled to take reading of time. Frictional loss through pipe components. Whenever a fluid flow through a pipe there will be some friction losses.

Monday 230 300 march 26 2018 ahmed abuaba feijie chen christopher. The difference in levels between piezometers A and B represents the total head loss h in the length of pipe l. Expt 1 - Friction Loses in.

The friction in. Major losses are associated with frictional energy loss that is caused by the viscous effects of the fluid and roughness of the pipe wall. Repeat the experiment for 06 and 09 bars of pressure difference.

Causes of friction loss can include the movement of fluid molecules against one another or against the inside surface of the pipe and bends kinks or sharp turns in hose or pipingThis experiment allows us to investigate different scenarios of piping particularly in roughness geometry and valves. Instead every component has its own minor head loss coefficient. Orta Doğu Teknik Üniversitesi.

V Mean velocity QA g. Similarly the entry. When solving for general friction factor using the Colebrook equation.

Pipe Friction Lab Report Mohammed Atheeq Nasir H00164902 Course. Science 6 B58EF Lecturer. Friction factor which is a function of the Reynolds number of the flow and the roughness of the internal surface of the pipe.

Further also recorded was the head loss due to pipe friction through measurements of pressure readings at various patter points on the pipe network. Fluids Lab report 4 lab pipe flow fluid mechanics laboratory section. This step first involved expelling any volume of air that could have been.

Fully open the gate valve and flow control valve. The lab measurements friction loss in pipe lab report. A short summary of this paper.

In hydraulic engineering it is customary to. Adjust the gate valve until 03 bar of head difference is achieved. Open the valves across she pipe along which the friction los will pe along which the friction loss will be calculated and ensure that all the other valves for the other pipes are closed.
