14)

When there is an excess potential energy during the fluid flow, it can be stored using O a. pressure relief valve. O b. pressure reducing valve. O C. accumulator. O d. pressure absorbing valve.

Initially, the gas pressure is greater than the outside atmospheric pressure. When valve 1 is opened, while valve 2 remains closed, the fluid level h1  ______.   Question 13 options:   stays constant   increases   decreases

Pipes/ Pump System Why are ball valves not as useful for throttling flow other as other valves types?

A.I) The term pressure drop refers to what in a hydraulic circuit a. The change in the flow rate in the hydraulic circuit b. The change in the fluid’s velocity in the circuit c. The pressure seen on the pressure gauge known as PG main d. The difference in pressure at the inlet of a component compared to the pressure at the outlet of the same component A.II) How are relief valve connected in a hydraulic circuit. a. In series with the pump b. In parallel with the pump c. In either series or parallel depends on the circuit d. Relief Valves are not connected to the pump

Initially, the gas pressure is less than the outside atmospheric pressure.   When valve 1 is opened, while valve 2 remains closed, the fluid level h1  ______.   Question 10 options:   decreases   stays constant   increases

Topic: Pneumatic Systems   Explain the following in at least 10 sentences: How do relief valves work?

Hello, I have some diagrams I have filled out for practice that I would like to use to study for an exam. Can someone double check them and suggest corrections if needed? Thank you

____ are installed in supply-water piping to prevent water hammer. Bypass valves, air chambers, pressure reducing valves, relief valves
