The discussion centers on calculating wind force using the formula: speed in mph squared multiplied by 0.0027 to yield pounds per square foot (psf). Participants seek a straightforward method for calculating psf based on water speed, prompting questions about the specifics of the water scenario, including the volume, speed, flow type, and surface area involved. Clarification is requested regarding the units of 0.0027, confirming it relates to the calculation of psf. The conversation highlights the need for precise parameters to effectively calculate water force. Overall, the thread emphasizes the importance of understanding both wind and water dynamics in force calculations.
