B. Mechanical work and power 1. Introduction a. Work done by force F on a body displaced distance s is Constant force F W = Fs ( kJ )
1 W = ∫ F ds ( kJ )
1 2 Variable force (2-22) W = area under curve 2 s b. Power supplied to body moving with velocity V: s1 s2 W = FV ( kW ) Lesson 4, Geof Silcox, Chemical Engineering, University of Utah 1 II. Energy and the First Law of Thermodynamics
c. Work and heat are processes, not properties. Work and heat are represented as areas on...
