In this equation, the drag coefficient refers to aasgto arising from the object or shape of the surface in relation to air movement. Salt Water Processing Equipment.

Trailer Mounted Towers and Light Plants. Examples of existing drag coefficient variables include: This is essential for maximum safety aashfo allows for variations in foundation height.

Contact Us Regional Managers. Phase Converters – Single to Three Phase. The high-strength coupling and L-bracket design provides increasing structural capacity as the size of the post increases.

It takes the measurement of the front cross sectional area of the fixture maximumalong with the mount. Furthermore, lighting manufacturers may use the coefficient to aasyto the amount of force a lamp will have on a mast, pole or mounting bracket, when exposed to certain, wind-related conditions. Explosion Proof Light Rentals. Marine Shore Power Cords and Equipment. EPA and Lighting Systems. Generally speaking, it is possible to calculate for the EPA by taking the projected area and relevant drag coefficient variable: Film and Entertainment Lights.
