First of all, the necessary accessories include the appropriate power supply (an AC adapter or a USB A-B cable to connect the board to your computer). The breadboard, connection cables and electronic components in THT technology will also prove useful (at the beginning, resistors with different values and diodes are mainly worth buying). Arduino is often sold in kits with accessories –… Continue reading What will be useful to learn how to use Arduino?

What types of Arduino are available and how do they differ?
There are currently over thirty versions of the Arduino board available on the market. They differ in the central systems used, the number and position of the pins, supported interfaces or additionally installed modules (e.g. Ethernet or Bluetooth). The most popular versions of Arduino used for electronic projects include Arduino Uno R33, Arduino Leonardo and Arduino Zero. Before you buy… Continue reading What types of Arduino are available and how do they differ?
How much is Arduino?
The price of the board depends on its model, the distributor and the contents of the set. On average, the cost of the original main module ranges from a few dozen zloty (e.g. Arduino Uno) to a few hundred zloty (e.g. advanced Arduino MKR models). It should be remembered that a suspiciously low price may indicate that you… Continue reading How much is Arduino?
Is Arduino suitable for beginners?
Yes, Arduino is one of the most recommended devices for beginners due to several aspects. First of all, they will appreciate the easy programming, the large number of available knowledge sources, the high compatibility with different devices and interfaces, and the wide range of available add-ons and extensions. The attractive price is another big and undoubted… Continue reading Is Arduino suitable for beginners?
What is Arduino made of?
Physically, Arduino is a PCB with a large number of tracks and soldered components on it. The board is available in many versions, but they all have some common features. They usually differ in the size and type of components used (for example, a slower microprocessor or no Bluetooth interface). The key element of the… Continue reading What is Arduino made of?
What is Arduino?
In general, Arduino is a small PCB (the size of a credit card) with a large number of components soldered on it. It is basically a ready-to-use development kit and an excellent learning base for beginners who are getting into electronics. However, it is also an excellent tool for professionals. The device has its own… Continue reading What is Arduino?
Transient Flow of a Gas Well
Gas flow in a reservoir under transient conditions can be approximated by the combination of Darcy’s law (rate equation) and the continuity equation. In general, which in radial coordinates reduces to From the real gas law, and therefore If the permeability k is considered constant, then Equation (4-64) can be approximated further: Performing the differentiation on the… Continue reading Transient Flow of a Gas Well
Gas Well Deliverability for Non-Darcy Flow
A more “exact” deliverability relationship for stabilized gas flow was developed by Aronofsky and Jenkins (1954) from the solution of the differential equation for gas flow through porous media using the Forchheimer (rather than the Darcy) equation for flow. This solution is where D is the non-Darcy coefficient and rd is the Aronofsky and Jenkins “effective” drainage radius, and… Continue reading Gas Well Deliverability for Non-Darcy Flow
Approximation of Gas Well Deliverability
The steady-state relationship developed from Darcy’s law for an incompressible fluid (oil) was presented as Equation. A similar relationship can be derived for a natural gas well by converting the flow rate from STB/d to MSCF/d and using the real gas law to describe the PVT behavior of the gas. Beginning with the differential form… Continue reading Approximation of Gas Well Deliverability
Gas Formation Volume Factor
The formation volume factor relates the reservoir volume to the volume at standard conditions of any hydrocarbon mixture. In the case of a natural gas, the formation volume factor, Bg, can be related with the application of the real gas law for reservoir conditions and for standard conditions. Thus, For the same mass, nR can be cancelled out… Continue reading Gas Formation Volume Factor
