Calculate the volumetric flow rate by dividing the volume by the time of collection:𝑉̇=𝑉/𝑡. Note: be careful with units (1m3= 1000 litres and 1 litre = 1000ml).

Analysis of Results

For each of the mercury manometer readings, convert the head loss in cm of mercury to head loss in cm of water by multiplying by 12.6.

• Calculate the volumetric flow rate by dividing the volume by the time of collection:𝑉̇=𝑉/𝑡. Note: be careful with units (1m3= 1000 litres and 1 litre = 1000ml)
• Calculate the average velocity: 𝑢=4𝑉̇/𝜋𝑑2.
• Calculate the Reynolds number: Re=𝜌𝑢𝑑/𝜇.
• Calculate the friction factor three different ways:1.Solve the Darcy equation for friction factor 𝑓and use your data to evaluate the value at each point.2.Use the Blasius equation.
