Compilation of lecture notes on ‘Steam Turbines’ for engineering students. Lecture Note # 1. Optimum Operating Conditions: Lecture Note # 2. Blade Height of Turbine: For impulse turbine the blade height at a particular section of a turbine will be function of mass flow rate (m), specific volume (v), area (A), and velocity of steam Let, P = pitch = distance [...]
Thermal Engineering Notes for Diploma and Engineering College Students! Note # 1. Thermodynamics System: Sometime we have to visit a general physician for certain health related problem. At that time, the physician examines our body for the accurate diagnosis of the illness. But, when we consult an ophthalmologist, he concentrates only a part of our body i.e., Eye. Thus, every [...]

Consider an elemental vertical cylinder of the body of height y and sectional area da. Let the intensity of pressure on the top end of the cylinder be p. The intensity of pressure on the bottom of [...]
Hydraulic Turbines: Lecture Notes, Suitability, Runaway Speed and Draft Tube. [With equations and examples] Note # 1. Introduction to Hydraulic Turbines: A hydraulic turbine is a prime mover which converts a substantial part of the potential and kinetic energy of flowing water to mechanical energy. Water stored in high level reservoirs like dams has enormous potential energy. This water having [...]
Here is a compilation of notes on water engineering. Note # 1. Construction of Open Wells: From the point of view of construction the open wells may be classified in the following three types: Type I: Wells with Impervious Lining: These are the most stable and useful type of wells. For constructing such a well first of all a pit [...]
Compilation of useful notes on metallurgy. Note # 1. Introduction to Metal Forming: Metal forming is the backbone of modern manufacturing industry besides being a major industry in itself. Throughout the world hundreds of million tons of metals go through metal forming processes every year. As much as 15-20% of GDP of industrialized nations comes from metal forming industry. Besides, [...]

The operation of a modern power system has become very complex. Frequency and voltage is to be maintained within limits in addition to ensuring reliability of power supply and for maintaining the frequency and voltage within limits it is essential to match the generation of active and reactive power with the load demand. For ensuring reliability of power supply it [...]
