Objectives

 T

• calculate Reynolds number and fanning

friction factor using measured flow rate and pressure drop.

 T

• understand the effect of Reynolds number

and roughness on friction factor.

 T

• calculate roughness parameter using

calculated experimental fanning friction factor.

Experimental Setup

Procedure

 Open one of the pipe inlet and allows flow through it.  Make sure that there are no air bubbles in the tubes

connected to the pressure gauge and taps, remove if any air bubbles present.

 Wait for the flow to reach steady state.  Measure the corresponding flow rate reading and

pressure drop reading.

 If flow rate is more than 10 lpm (litre per minute) use

flow meter 1 otherwise if flow rate is below 10 lpm then use flow meter 2.

 Close the values slightly to change the flow rate and

hence take 6 readings for a pipe.

Safety precautions

 Never leave both the bypass of the pump

and all the values of pipes closed while the pump is running.

 Never use flow meter 2 when the flow is

above 10 LPM.

 Glass Pressure tabs should be connected

carefully.
