WebAngular acceleration α is defined as the rate of change of angular velocity. In equation form, angular acceleration is expressed as follows: α = Δ ω Δ t, 10.4. where Δ ω is the change in angular velocity and Δ t is the change in time. The units of angular acceleration are rad/s /s, or rad/s 2. If ω increases, then α is positive. WebFeb 20, 2024 · Viscosity has units of (N / m2) s or Pa ⋅ s. Flow is proportional to pressure difference and inversely proportional to resistance: Q = P2 − P1 R. For laminar flow in a tube, Poiseuille’s law for resistance states that R = 8ηl πr4. Poiseuille’s law for flow in a tube is Q = (P2 − P1)πr4 8ηl.
