What we have learnt
- The calculation of power required and pressure at pump suction can be done using Bernoulli's equation and accounting for head losses.
- Pipe networks can be connected in series or parallel, leading to different rules for head losses and flow rates.
- The Hardy Cross Method serves as an iterative approach to solve complex pipe network systems, ensuring the continuity of flow and balance of head losses.
Key Concepts
- -- Bernoulli's Equation
- A principle that relates pressure, velocity, and height in fluid flow to perform energy calculations.
- -- Head Loss
- The reduction in total head (energy) of the fluid as it moves through a pipe due to friction and other factors.
- -- Hardy Cross Method
- An iterative method used in hydraulic engineering to analyze flow distribution in pipe networks.
- -- Minor Losses
- Losses in fluid energy due to phenomena such as sudden expansions, contractions, and fittings in piping systems.
- -- Major Losses
- Loss of head in the flow due to friction along the length of the pipe.
