438 CHAPTER 4. KINEMATICS 4.64 Chapter 4, Problem 64 We can apply the Reynolds Transport Theorem to this problem if we consider the Spectre thugs to be a system and Spectre headquarters a control volume. Since the Spectre headquarters building is stationary, u rel = u . Thus, the Reynolds Transport Theorem tells us ˙ N 007 = d dt 888 V ρ dV + 8 s 8 S ρ ( u · n ) dS where ˙ N 007 is the rate at which Bond is terminating thugs and ρ is the number density of thugs, i.e., number of thugs per unit volume. Also, by definition, the number of live

Unformatted text preview: thugs in Spectre headquarters, N , is N = 888 V dV So, the Reynolds Transport Theorem simplifies to N 007 = dN dt + 8 s 8 S ( u n ) dS = dN dt + nvA Therefore, the rate of change of live thugs in Spectre headquarters is dN dt = N 007 nvA Note that Agent Leiters arrests outside of the control volume has no impact on the rate of change of live thugs within the control volume....
