WebWork and energy in rotational motion are completely analogous to work and energy in translational motion, first presented in Uniform Circular Motion and Gravitation. Now, we solve one of the rotational kinematics equations for αθ. We start with the equation. ω 2 = ω 0 2 + 2 αθ. 10.57. WebBesides, the resemblance in average Nusselt number and friction factor are presented. To grasp the effectiveness of heat transfer, thermal efficiency has been calculated to find the optimum condition, and it reveals that the critical corrugation height, h = 0.0318D at Re τ = 314, f c = 18, φ = 2% corresponds to higher thermal efficiency.
