Textbook Question
Chapter 7, Problem 22ICA
A manufacturing process uses 10 pound-mass of plastic resin per hour [lbm/h]. Rather than using a traditional unit system, we wish to use an unusual unit system called the FFF system: furlong-firkin- fortnight. One firkin is equal to 40 kilograms [kg] and one fortnight is 14 days [d]. Convert this processing rate to units of firkin per fortnight.
