Pascal's Law

Pascal's Law

What is Pascal's law?

Pascal's law states that the pressure exerted on an enclosed space is equal in all directions.

One of Pascal's laws is a hydraulic jack.
Hydraulic jack

The hydraulic jack has 2 sections, 1 large section and 1 small section, the small section is called the large section of the output section. These hydraulic jacks are filled with a liquid, usually oil.

If we apply a force on a small surface cross section or input then the liquid will get pressure with the formula:

P1 = F1/A1

Des : P = Pressure (N/m² )
         F = Power style (N)
         A = Cross-sectional area (m²)

Then the pressure will be facing in all directions, to the wall and to the large section or output section. If the force from surface 1 is continued to surface 2 then the pressure will cause a force on surface 2, namely:

P2 = F2 / A2

Des : P = Pressure (N/m² )
         F = Power style (N)
         A = Cross-sectional area (m²)

As a result of this pressure, a large cross-section will be able to lift objects that are above its surface. So when pressure is applied to a small surface (A1), the same pressure will be received by a large cross-section (A2).

P1 = P2

Or

F1 / A1 = F2 / A2

Problems example :

A hydraulic pump has an input cross-sectional diameter of 4 cm and an output cross-sectional diameter of 80 cm. If the input force is 50 N then what is the force produced from the output cross section?

Is known :
A1 = 3,14 x 4 ² = 50,24cm²= 0,005024 m²
A2 = 3,14 x 80 ² = 20096  cm² = 2.0096  m²
F1 = 50 N

Asked :
F2 = ... ?

Answer :

P1 = P2
F1 / A1 = F2 / A2
50 / F2 = 1 / 400
F2 = 50 / 0,0025
F2 = 20000 N

Pascal's name itself is taken from the name of a famous physicist from France named Blaise Pascal.

Thus the discussion of Pascal's law, may be useful.

Text And Mtext In Autocad

The Difference Between "Text" And "Mtext" In Autocad And How To Convert It In operating AutoCAD we often encounter or use writing with the aim of providing information, showing something, etc. so that our drawings are easier to understand. To write in AutoCAD, we know that there are two options, the first is "TEXT" and the second is "MTEXT". So what are the differences between the two? TEXT For "text" itself we can call it single text or single writing. So if we use "text" we can only write one sentence in one piece of text. The disadvantage of this "text" is that it doesn't have any editing menu, we can't adjust or adjust our needs in this paper, instead we must first enter the properties menu. This means that from this "text" we can only edit the written content. To use this "text" we can use the command type "DT" then press enter. MTEXT As for "mtext" itself is an ab...

Genset Heating Procedure

Genset Heating Standard Procedure Genset is one of the equipment that functions to convert mechanical energy or rotation of the rotor into electrical energy. The generator has two main parts, namely the motor generator and the generator engine (usually a diesel engine), both of which are connected by a shaft. The generator itself has two main parts, namely the rotor and stator. The stator is the stationary part, while the rotor is the rotating part. This generator works when the genset control panel receives input if the power source from PLN dies, then the PLC or ATS (automatic transfer switch) will give an order to the genset control panel to turn on the generator, this is done automatically. What if the generator has to be turned on manually, for example when heating the generator? Genset as one of the supporting utility facilities of a building must of course be maintained regularly, one of which is heating the generator as one of the genset maintenance procedures. To warm up the g...
