5 cards from this section. Quick, good the night before a test.
What is the friction factor given in this section?
Refer back to the section's parameters.
What is the total length of the pipe in the problem?
Find this number at the beginning of the section.
What is the friction factor value provided in the design problem?
Look for the specific values in the problem description.
Is the entry loss coefficient considered to be zero?
Check how the entry and exit coefficients are defined.
A water system has multiple fittings leading to a total loss coefficient of 12. Calculate the energy losses in the pipe when the flow velocity is 3 m/s. Use the Darcy-Weisbach equation.
Refer to the friction factor and combine it with your additional fittings.
Calculate the required horsepower for a pump needed to move water from a supply tank 20 m deep through a system with a total head loss of 35 m. Include energy losses in your calculations.
Review horsepower conversion and consider efficiency factors for a complete calculation.
