science L4.6 Force & Pressure in Pipework Quiz

Which material offers the least resistance to the flow of water?

• Copper tubes

• Plastics

• Low Carbon Steel

• Machine made bends

What effect do elbows and bends have on the flowrate?

• Increase the flowrate

• Decrease the flowrate

• Have no effect on the flowrate

• Increase the pressure

How does the length of the pipe run affect the pressure and flow rate?

• Increases both pressure and flow rate

• Decreases both pressure and flow rate

• Increases pressure but decreases flow rate

• Decreases pressure but increases flow rate

What happens to the volume of water or gas when the pipe size increases?

• Increases

• Decreases

• Remains the same

• Cannot be determined

What effect do valves and stop taps have on the pressure and flow rate?

• Increase both pressure and flow rate

• Decrease both pressure and flow rate

• Increase pressure but decrease flow rate

• Decrease pressure but increase flow rate

What is the effect of a pipe size reduction on the pressure and flow rate?

• Increases both pressure and flow rate

• Decreases both pressure and flow rate

• Increases pressure but decreases flow rate

• Decreases pressure but increases flow rate
