4 cards from this section. Quick, good the night before a test.
What is the formula for calculating head loss?
Look for terms related to flow and energy in the equations.
What must be true at each junction in a pipe network?
Think of the concept of balance.
What does the Hardy Cross Method aim to achieve?
Think about what issues the method addresses.
The equation for head loss is expressed as HL = ?
Look for terms related to flow rate in the equation.
In a city water distribution network, the total inflow into a junction is 100 L/s, with three outgoing pipes sharing the flow. If the flows are set to 50 L/s, 30 L/s, and 15 L/s, how would you adjust these flows using the Hardy Cross Method?
Look for how adjustments affect the overall outflow.
Given a pipe network with different diameters and lengths, calculate the head loss for a situation where the flow rates are known. How would the Hardy Cross Method change these calculations?
Remember to focus on the relationship between Q and HL during your calculations.
