Fluid Mechanics & Hyrology

Fluid Mechanics

Fluid mechanics is an undergraduate subject for civil engineers which basically deals with fluids including, liquids, gases and plasmas. Different equations and formulas are there to calculate the discharge, velocity etc of fluids and many other techniques are available which all are discussed under this subject.

Bernoulli’s Apparatus   Venturi meters   Types of orifices with respect to type & Shape
Types of orifices with respect to Edge shape & Nature of discharge  Jet of water  vena contracta  Orifice  
Types of Notches   Venturimeter 1  Venturimeter 2  Hydraulic Coefficients Cc Cv Cd  1
Hydraulic Coefficients Cc Cv Cd 2  Discharge Through Rectangular Notch  Discharge Through Triangular Notch
Center Of Pressure 1   Center Of Pressure 2   Center Of Pressure 3  Metacentric Height  Tube type viscometer 1
Tube type viscometer 2


Hydrology on the other hand is the study of water, its distribution, quality and cycle. It can be subdivided into surface hydrology and marine hydrology. There are different techniques to measure the velocity and discharge of water which are discussed below. The basic hydraulic concepts are also mention below for students to enhance their knowledge.

Current Meter   Current Meter 1  Current Meter 2  Current Meter 3
Current Meter 4  Current Meter 5  Current Meter 6  Current Meter 7

  1. Dear All I need these books urgently, if any one have please email me:
    1) Hydraulic Design of Stepped Cascades, Channels, Weirs and Spillways
    2) Hydraulics of Spillways and Energy Dissipators by R.M.Khatsuria

  2. i need the standard book for fluid mechanics 10th ed finnemore..NOT SOLUTIONS BUT THE ACTUAL BOOK!! please and thank you =]
