Now, the velocity of the particle is always tangent to the curve. If we set v as the magnitude of the particle velocity, then Using the chain rule of Calculus we can write Since, we can write This gives us Substituting equation (4) into equation (3) we get As a result, ...
Work-done Under a Constant ForceTo derive an expression for the work done under a constant force, let us assume that an object with final velocity v, initial velocity u, covers a distance s, under a constant acceleration a. The equation of motion of the object can be given as:v2...
Also your solver might adjust U values not only after solving momentum equation. So make sure that your are limiting after each calculation step of U batta31March 15, 2013 07:09 Thank you Omkar! The problem was exactly on the patches, since I had forgotten to loop on them. By adding...
The specific work can on basis of the energy equation be expressed with the head as: w = g h (6) where h= head (m) g= acceleration of gravity (m/s2) Transformed to express head: h = w / g (7) Example - Specific Work of a Water Pump A water pump works between 1 bar (105...
The power equation is: P = VI where: P is power in watts (W) V is voltage in volts (V) I is current in amperes (A). This formula tells us that the power consumed by an electrical device is directly proportional to the voltage applied to it and the current flowing through it. ...

For example, if the predicted maximal heart rate is 200 beats per minute (BPM) and the test target heart rate of 90% of 200 BPM is achieved at a work load of 8 METs, then the max functional capacity may be estimated from the equation: 8 METS = 90% of maximal functional capacity; ...
Precisely, first we use the concept of power to construct a Lyapunov functional appropriate to furnish stability in the mean (control of perturbations to velocity and positions), when 蔚 has a minimum atC*; then introducing thefree work we deduce apivot equation for the study of nonlinear ...
algorithm. The first (equation 1) is the velocity equation, where each particle in the swarm updates its velocity using the computed values of the individual and global best solutions and its current position. The coefficients ofandare acceleration factors related to the individual and social ...
