• ### OPEN CHANNEL HYDRAULICS FOR ENGINEERS

The textbook of Open Channel Hydraulics for Engineers, also called Applied Hydraulics, emphasizes the dynamics of the open-channel flow, by attempting to provide a complete framework of the basic equations of motion of the fluid, which are used as building blocks for the treatment of many practical problems. The structure of the document, with seven chapters totally, follows a logical sequence from a description and classification of Fluid Mechanics and Open Channel Flows, as reviewed in Chapter 1. A development of the basic equation of motion for uniform flow is encountered in Chapter 2.

• ### Open channel hydraulíc for engineers

The subject of Open Channel Hydraulics for Engineers, also called Applied Hydraulics, is a subject required not only for Hydraulic Engineering students but also for other engineering fields involved, such as Construction Engineering, Transportation Engineering and Environmental Engineering. It follows the previous subject named Fluid Mechanics. The knowledge of open-channel hydraulics, which is essential to the design of many hydraulic structures, has made advances by leaps and bounds.

• ### Open channel hydraulics for engineers. Chapter 3 hydraulics jump

In this chapter, the specific-energy concept is introduced and, then, the momentum principle is applied to open-channel flows. The hydraulic jump and its types are defined and classified. This chapter introduces how to determine the direct and submerged hydraulics jump; their characteristics are presented

• ### Open channel hydraulics for engineers. Chapter 2 uniform flow

The chapter on uniform flow in open channels is basic knowledge required for all hydraulics students. In this chapter, we shall assume the flow to be uniform, unless specified otherwise. This chapter guides students how to determine the rate of discharge, the depth of flow, and the velocity. The slope of the bed and the cross-sectional area remain constant over the given length of the channel under the uniform-flow conditions. The same holds for the computation of the most economical cross section when designing the channel.

• ### Open channel hydraulics for engineers. Chapter 4 non uniform flow

Linking up with Chapter 2, dealing with uniform flow in open channels, it may be noted that any change in the flow phenomenon (i.e. flow rate, velocity, flow depth, flow area, bed slope do not remain constant) causes the flow to be non-uniform. This chapter will discuss the effect of change in any one of the above quantities, including specific energy, critical depth and slope, and flow types. How to draw water surface profiles will also be introduced.

• ### Open channel hydraulics for engineers. Chapter 1 introduction

This lecture note is written for undergraduate students who follow the training programs in the fields of Hydraulic, Construction, Transportation and Environmental Engineering. It is assumed that the students have passed a basic course in Fluid Mechanics and are familiar with the basic fluid properties as well as the conservation laws of mass, momentum and energy. However, it may be not unwise to review some important definitions and equations dealt with in the previous course as an aid to memory before starting.......

• ### Heat Transfer Applications for the Practicing Engineer

After a review of the literature, the author has concluded that the concept of heat transfer was first introduced by the English scientist Sir Isaac Newton in his 1701 paper entitled “Scala Graduum Caloris.”(1) The specific ideas of heat convection and Newton’s Law of Cooling were developed from that paper

• ### Open channel hydraulics for engineers. Chapter 5 spillways

Spillways are familiar hydraulic structures built across a stream to control the water level. This chapter emphasizes the classification of weirs and spillways as well as the application of hydraulic formulas for designing their shape and dimensions.

• ### Open channel hydraulics for engineers. Chapter 7 unsteady flow

This chapter introduces issues concerning unsteady flow, i.e. flow situations in which hydraulic conditions change with time. Many flow phenomena of great importance to the engineer are unsteady in character, and cannot be reduced to steady flow by changing the viewpoint of the observer. The equations of motion are formulated and the method of characteristics is introduced as main part of this chapter. The concept of positive and negative waves and formation of surges are described. Finally, some solutions to unsteady flow equations are introduced in their mathematical concepts.......

• ### Open channel hydraulics for engineers. Chapter 6 transitions and energy dissipators

The term "transition" is introduced whenever a channel's cross-sectional configuration (shape and dimension) changes along its length. Beside it, in the water control design, engineers need to provide for the dissipation of excess kinetic energy possessed by the downstream flow. Formulas for design calculation of transition works and energy dissipators are presented in this chapter
