Derivation of Material Acceleration (Section 4-1, Çengel and Cimbala) Recall the chain rule : If f is a function of two variables, t and some variable s which is itself also a function of t , then we take the total derivative of f with respect to t as follows: df f dt f ds f f ds dt t dt s dt t s dt ∂∂ =+= + Now let’s apply this chain rule to the time derivative of the fluid particle’s velocity: Thus, the acceleration of a fluid particle is calculated using the chain rule as follows:
