MASS, BERNOULLI, AND ENERGY EQUATIONS This chapter deals with three equations commonly used in fluid mechanics: the mass, Bernoulli, and energy equations. The mass equa- tion is an expression of the conservation of mass principle. The Bernoulli equationis concerned with the conservation of kinetic, potential, and flow energies of a fluid stream and their conversion to each other in

Ebbinghaus’s Forgetting Curve For example, if Ebbinghaus took 12 trials to learn a list and 9 trials to relearn it several days later, his savings score for that elapsed time would be 25 percent (12 trials – 9 trials 3 trials; 3 trials 12 trials 0.25, or 25 percent). Using savings as his measure,

Chapter 5 Venturimeter & Orificemeter Applications of the Bernoulli Equation The Bernoulli equation can be applied to a great many situations not just the pipe flow we have been considering up to now. In the following sections we will see some examples of its application to flow measurement from tanks, within pipes as well as in open channels. 1.
