ENABLING OBJECTIVES (Cont.)
DEFINE the term head with respect to its use in fluid flow.
EXPLAIN the energy conversions that take place in a fluid system between the velocity,
elevation, and pressure heads as flow continues through a piping system.
Given the initial and final conditions of the system, CALCULATE the unknown fluid
properties using the simplified Bernoulli equation.
DESCRIBE the restrictions applied to Bernoullis equation when presented in its simplest
EXPLAIN how to extend the Bernoulli equation to more general applications.
RELATE Bernoullis principle to the operation of a venturi.
DEFINE the terms head loss, frictional loss, and minor losses.
DETERMINE friction factors for various flow situations using the Moody chart.
CALCULATE the head loss in a fluid system due to frictional losses using Darcys
CALCULATE the equivalent length of pipe that would cause the same head loss as the
minor losses that occur in individual components.
DEFINE natural circulation and forced circulation.
DEFINE thermal driving head.
DESCRIBE the conditions necessary for natural circulation to exist.
EXPLAIN the relationship between flow rate and temperature difference in natural

reactor coolant system and other heat removal systems.
DESCRIBE how to enhance natural circulation flow.
DEFINE two-phase flow.
