Question
Which of the following statements are correct about hydraulic systems? (Check all that apply.)
It uses potential energy, which can be due to height or flow
The main force for hydrostatic pressure is our atmosphere
The hydrostatic pressure is the same throughout a given area defined by height of water column
When you want SI units of pressure, you use the equation P = 0.43 x h
It uses potential energy, which can be due to height or flow
The main force for hydrostatic pressure is our atmosphere
The hydrostatic pressure is the same throughout a given area defined by height of water column
When you want SI units of pressure, you use the equation P = 0.43 x h
Explanation / Answer
It uses potential energy, which can be due to height or flow this is true as the hydraulic system uses potential energy and kinetic energy and also pressure of the fluid flow.
The main force for hydrostatic pressure is our atmosphere. This is false because main force comes from the hydraulic fluid.
The hydrostatic pressure is the same throughout a given area defined by height of water column. This is true as the hydrostatic pressure is given by P = g h
When you want SI units of pressure, you use the equation P = 0.43 x h. This is false. For SI units of pressure
P = 9.8 * h is used.
