FEN 202: ENGINEERING MATHEMATICS III TEST (CARRY-OVER) 2021

  FEN 202: ENGINEERING MATHS III (TEST) 1.       1   The velocity of a chemical reaction is given by dx/dt = k(a – k) where x is the amount transferred in time t, K is a constant and a is the concentration at time t=0 when x=0. Solve the equation and determine x in terms of t   2.       2.     The current drawn in the electric circuit as shown below is given by the equation “Ri + L dl/dt = 0” where L and R are Inductance and Resistance respectively as constants respectively, prove that          I = Ie – Rl/L     3.     3.       For an adiabatic expansion of   a gas Cv dp/p + Cp dv/v = 0 Where Cp and Cv are thermodynamic constants given. N x Cp/Cv Show that PV n = constant
