What are the two common main components of a water distburtion system?

You are designing a pumped water supply system for a small township. What is the most appropriate way to manage pump operation?

Consider the flow in a pipeline immediately upstream and downstream of a pump. What difference would  you expect to see at these two locations?

You're adding a pump to an existing pipeline and have been given the pump curve for the pump that relates the head to the flow rate and the efficiency curve for the pump.

How might you determine the new flow rate for the pipeline?

Two pumps are installed in parallal. The flow rate through Pump A is , and the head provided by Pump A is . The flow rate through Pump B is , and the head provided by Pump B is .

Which of the following correctly gives the total flow rate, , and the total head change, , across the pump group? Assume that losses in the connecting pipes are negligible.

Two pumps are installed in series: Pump A followed by Pump B. The flow rate through Pump A is , and the head provided by Pump A is . The flow rate through Pump B is , and the head provided by Pump B is .

Which of the following correctly gives the total flow rate, , and the total head change, , across the pump group?

True or false: Cavitation occurs in a pipeline when the water pressure drops below atmospheric pressure.

Match each valve image with the correct valve type.

What is the value of the entrance loss coefficient for a sharp-edged pipe entrance?

You are selecting a valve for a pipeline that will remain fully open during normal operation. The goal is to minimise head loss. Which valve would you use?
