Pressure and Data Acquisition: A Comprehensive Guide
Pressure Problem 7
Pressure (Pascal or N/m2) = Force (N) / Area (m2)
Air pressure decreases with increasing altitude
Static pressure measurement= NO MOTION Dynamic pressure measurement= WITH MOTION. Absolute pressure is measured relative to a vacuum (0 N/m2). Gauge pressure is relative to ambient atmospheric pressure. Differential
Pressure is like gauge pressure, but a specific reference pressure is used instead of the atmospheric pressure.
Locations to measure differential pressure: ACROSS FANS,

1. Supports in Art
1.1. Material Properties of Supports
The materials that form a support give it a series of qualities such as absorption, flexibility, transparency, and texture. Examples include:
- Absorbent: Paper, cardboard, plaster walls
- Flexible: Paper, cardboard, fabric
- Rigid: Walls, wood, ceramic
- Transparent: Plastic wrap, celluloid, acetate
- Opaque: Cloth, wood, paper, walls
- Smooth: Satin and smooth papers and cardboards
- Textured: Rough papers, walls, wood

Understanding and Troubleshooting PC Power Supplies
The Power Supply Unit (PSU)
The PSU is a crucial component that converts AC power to DC and delivers the required voltages to various computer parts. It’s physically attached to the case and often uses a fan for cooling.
Types of Power Supplies
There are two main types of PSUs:
- Switching: More efficient, smaller, and lighter, but can generate electromagnetic interference (EMI).
- Linear: Uses a transformer, generates less EMI, but is larger and less efficient.
IR Remote Control for Servo Motor with Arduino
Code Explanation
This code controls a servo motor using an IR remote and an Arduino. It includes functions to decode IR signals, validate remote codes, and perform actions based on the received key presses.
IR Remote Codes
The code defines arrays to store IR codes for both white and black remotes, along with their corresponding key names. These codes are specific to the Robojax IR remote but can be modified for other remotes.
White Remote Codes (Non-PCB Version)
unsigned int whiteRemote[] = { ... };
