○ Application of Duct Checker
- Pipe dimensions are easy to determine by the constant pressure method
- The friction reference unit loses resistance, the standard wind speed can be set freely
- Display the actual loss resistance and wind speed etc in decision tube
○ Summary of Duct Checker
Pipe sizing methods, constant pressure method, a collection method, total pressure method, which has the constant velocity method, as the most widely used method , the constant pressure method (equal friction loss method). (All pipe sizing methods use the same value on the friction loss per 1m tube) would normally be determined by a pipe Toka flow chart designed for the rules of slip, the use of these programs.
Duct Checker operating environment
Operating System: Windows 9X, Windows NT 4, Windows 2000, Windows XP, Windows 7, Windows 10.
○ Go to the Duct Checker formula input
When entering the airflow rate, you can enter mathematical expressions.
exp.1 1500 + 1500 → 3000
exp.2 500 * 3 + 1000 → 2500
You can only use four arithmetic operations (+, -, *, /), powers (^), etc.
SIN, COS, TAN, ASIN, ACOS, ATAN, LOG 10, LN, EXP, SQR, SQRT
Can be used.
(Note: angle in degrees)
exp.3 ATAN (1) → 45
exp.4 LOG 10 (1000) → 3
Variables can also be used. Variables begin with the letter "A ... Z _", followed by alphabetic characters, underscores, and numbers. Two-byte codes (Kanji or Hiragana) cannot be used.
(Note: Upper and lower case letters are not distinguished.)
exp.5 ABC = 150 → 150
exp.6 ABC * 5 → 750
exp.7 PI → 3.14159265358979
○ Duct Checker start option
[/ eng] Required in English.
[/ jpn] Starts with Japanese mode.
(In the absence of the above option, it starts with Japanese for Japanese OS and English mode for other language OS)
