This notation also allows us to directly express the derivative of an expression … I understand the concept explained in this video. A question arise now. Consider a … WebApr 3, 2024 · The average velocity of a particle is the rate of change of its position over time. If the particle moves forward, its velocity is positive, and if it moves backwards, its velocity is negative. Velocity is obtained by differentiating its displacement, x x, in terms of t t. v = dx dt v = d x d t or x = ∫ vdt x = ∫ v d t Speed

WebMar 28, 2012 · The design velocity for the coil depends on application. For a given coil,if the face velocity exceeds a threshold, (typical 500 to 600 fpm) there is the risk of water carryover off the coil. This can cause water issues in the duct or plenum. If the face velocity drops below some threshold, (typ 225 fpm) the air through the coil may not be ...
