Doran – Bioprocess Engineering Principles – Solutions Manual _ Īnswer: 167 s–1 (d) From Table A.8 (Appendix A): 1 W = 1 J s–1 From Table A.7 (Appendix A): 1 J = 9.869 × 10–3 l atm From Table A.1 (Appendix A): 1 m = 3.281 ft 1 min = 60 s As explained in Section 2.4.6, ☌–1 is the same as K–1. As revolutions is a non-dimensional quantity (Section 2.1.2), the units of rpm are min–1.
