Water Temperature: 298K Density: 1000kg/m 3 Viscosity: 0.91 CP 0.00091N.s/m 2 Test Section Diameter: 10.25 MM 0.01025m Area (M) : 0.008252m 2

The document contains experimental data measuring the flow rate of water through a test section with varying heights. Key parameters recorded include water temperature, density, viscosity, test section diameter, area, quantity and time of water collected, mean velocity, Reynolds number, inlet and outlet heads, friction head loss, friction factor, and volume flow rate. Graphs of log(V) versus log(hf) were to be plotted from the experimental data.

Sample Calculation
1. Area= (/4)*D^2
= 0.008252
2. Q= Volume/ Time
= 0.380/0.045 = 8.4444
3. Mean Velocity = Qave/A
= 7.7847*(0.001/60)/0.008252
= 0.015723
4. Log (V) = log (0.015723) = -1.79585
5. Re = Density*Mean velocity*Diameter/Viscosity
= 1000*0.015723*0.01025/0.00091
= 177.1
6. Log (Re) = log (177.1) = 2.24822
7. Hf = h1-h2
= 325-115
= 210
8. Log (Hf) = log (210) = 2.32222

9. f`= 64/ Re
= 64/177.1
= 0.361378
10. Log (f`) = log(0.361378) = -0.442039
