How To Calculate Air Velocity

How To Calculate Air Velocity. Air flow equations for working out the velocity of air coming through a hose or tube and the pressure loss of the air going through these. V = velocity of the object.

Colebrook Equation from www.engineeringtoolbox.com

V = velocity of the object. The air constant, or the drag coefficient of the object, is dependent on the shape of the object and is a dimensionless. The temperature in degrees rankine is an absolute reference and is t in degrees f + 460.

Air velocity in a space influences the convective heat exchange between occupant and the indoor environment (seppanen and kurnitski, 2013 ). The mean velocity of air vessel given length of stroke formula is defined as the time average of the velocity of a fluid at a fixed point, over a somewhat arbitrary time interval counted from.
