• Measure the length and diameter of the pipe. • Valve 3 should also be open. • Record the heights of mercury in the manometer and note it under h1 and h2. • Using stop watch and a beaker measure the flow rate for laminar flow about 4-5 different times. III. Turbulent Flow • Valve 1 and 3 should be closed now and only valve 2 should be open now. • Using stop watch and beaker measure the flow rate again 4-5 different times. IV. Calculations • Calculate the velocity (m/s) and the Reynolds’ number for each flow rate. • Hence, find the value of friction factor from the calculated head loss for both Laminar and Turbulent flow rates. • If the flow is Laminar (i.e. Re4000), use Blasius smooth pipes. • Using the calculated values plot a graph between log (Re) and log (f). • Further, using Prandtl and Karman’s formula for rough pipes substitute the value for Reynolds’ number and friction factor and hence, find the value of pipe roughness ks. RESULTS After tabulating the obtained results, we can observe the value of friction factors for each flow rate are as follows: And we obtain the following log (Re) vs. log (f) graphs for Laminar flow: And for Turbulent
