Dimensions
and Units used in Fluid Mechanics
In a Nutshell: Of the four basic
dimensions in fluid mechanics force,
mass, length, and Physical Quantity FLT System MLT
System
The
British Gravitational System (BG) and the International System (SI) are used in the study of fluid mechanics. The table below lists common units used.
Length: 1 inch = 2.54 cm, 1 ft = 0.3048 m Pressure:
1 lb/in2 = 6.894 N/mm2 Energy: 1 Joule = 1 N m Force:
1 N = 1 kg m / sec2 Gravitational
Constant: 1 g = 32.174 ft/sec2 1 g
= 9.807 m/sec2 oF =
(9/5)oC + 32, oC =
(5/9)(oF – 32), Absolute temps oR
= oF + 460, Absolute temps oK = oC + 273
Also note: 1 N/mm2 = 1 mPa |
