Apart from corrections in the text, this edition includes substantial revision of Chapter 2. We have explicitly brought out the link between a control volume approach to problem solving in fluid mechanics and a boundary-value formulation stemming from Navier-Stokes equations. The utility of momentum and energy equations for analysis at the scale of a control volume has been highlighted. The fact that Bernoulli equation is a special form of the more general energy equation is discussed. Examples leading to limiting cases of flow rates and forces are included. Additional examples have been introduced and details of calculations are presented. The list of unsolved examples has been expanded to reflect the new text of Chapter 2.

The authors are conscious that the subject of fluid mechanics continues to be important and of interest. Accordingly, Comments received on previous editions are gratefully acknowledged.

As always, we welcome responses from students and colleagues.
