3 cards from this section. Quick, good the night before a test.
What is a hydraulic gradient line?
Think about the pressure and elevation of the fluid.
What does a pitot tube measure?
Consider how we assess flow speed in a pipe.
What does the hydraulic gradient line coincide with in a pipe flow?
Where does the flow exit in a pipe system?
True or False: The energy gradient line decreases steadily due to energy losses.
Think about how energy dissipates in fluid motion.
In a long pipeline with a sudden enlargement from 150mm to 300mm diameter, water flows at 2m/s and creates turbulence. Calculate the pressure loss due to this enlargement and discuss how to reduce it.
Focus on diameter ratio and initial versus final velocities.
A pump elevates water from a reservoir to a storage tank 30m higher. If the pump is 85% efficient and the motor input is 10kW, calculate the flow rate to the tank based on the pump characteristics.
Use the given height and efficiency to find usable power.
