A system needs a valve that can create a controlled pressure drop by partially restricting flow. Which valve would you use?
What is the value of the exit loss coefficient for flow leaving a pipe into a large reservoir?
Which energy equation(s) correctly describe the system shown above? Select all that apply.
A pipe has a diameter of 0.2m and an average roughness height of 0.25mm.Calculate the relative roughness. Enter your answers to 3 significant figures.
Ignoring frictional losses, what quantities will be conserved between the inlet at (1) and the outlet at (2)?
The pipe area at the inlet (1) is 1 m2 and the velocity is 0.2 m/s.If the area at the outlet (2) is 0.4 m2, calculate the velocity in m/s.
The flow rate at inlet (1) and outlet (2) is 2 m3/s and the pipe area is 0.5 m2 in both locations.If the angle a is 30o and the density of the fluid is 1000 kg/m3, calculate the force on the fluid in the x direction (in Newtons).
Water is leaving a pipeline as a free jet. Which of the following drawings of the total energy line (TEL) and hydraulic grade line (HGL) is correct?
Which of the following drawings of the total energy line (TEL) and hydraulic grade line (HGL) is correct?
You're looking at a pipeline and are concerned that negative pressures might be developing. If you know the pipe elevation and the positions of the hydraulic grade line (HGL) and total energy line (TEL), what feature would you look at to determine if dangerous negative pressures are developing.
