1. Derive the general design equations for the CSTR, batch, and PFR and then specify them for the case of no volume change 20. A string vibrates with time as given in the table below: Data Point (i) Position (x) Time (t) 1 3.2 0 2 -2.5 2.5 3 1.1 5 It is believed that this string vibrates with time according to the equation x = A cos(t) . (a) Determine the value of A that gives the least-squares in the general case of N points using the least-squares method (b) Generalize this formula to the case of N=3 points and expand the summation (c) Calculate the value of A that gives the least squares 3. The reaction A

Unformatted text preview: → B takes place at constant temperature in a steady-state backmix reactor. The reactor volume was 10 L, and the reactor was operated so that the molar flow rate of A is the feed was 100 mol/h and the molar flow rate of A in the product was 5 mol/h. (a) What was the molar flow rate of B in the product if the molar flow rate of B in the feed was zero? (b) What was the rate of the reaction? (a) Determine a formula for the cross-sectional area A with regards to z. (b) Using the mass balance and the result of part (a) determine the velocity, v Z , of the fluid in the constriction for any position....
