Fluid Mechanics 

This is a in depth series of videos for hydraulic machines. My objective is to teach you everything you need to get that job or masters admission you want. I have put a lot of effort to make these series of lectures of and level that top level coaching indoors in this country has so that students who cannot go to a coaching obsidian can be benefited. These lectures are focused to help GATE, ESE, BARC, ISRO, DRDO, PSUs aspirants.

Introduction to the Course (in Hindi)

Pumps: Basics (in Hindi)

Pump Performance Curves (in Hindi)

Cavitation is local boiling of a liquid which causes noise and vibration.

Boiling and Cavitation (in Hindi)

We will learn about Available NPSH and Required NPSH.

Types of NPSH (in Hindi)

We cover reciprocating pumps advantages and disadvantages of reciprocating pumps.
- Air vessel
- double acting pumps
- lobes pump
- gear pumps
- screw pumps

Positive Displacement Pumps (in Hindi)

We learn about which pump combination to use when by using pump performance curve.

Pumps in Series and Parallel (in Hindi)

The principle of centrifugal pump is discussed here.
-Different components of it like eye of impeller, scroll, strainer, one way valve, casing. 
- Why we have gradually increasing cross section in pumps will be explained.

Centrifugal pumps #1(in Hindi)

Velocity Triangles for Pumps (in Hindi)
All lot of students don't really know how velocity triangles are actually made. I'm here to show you the correct method. I'll show you how you can your simple mathematics to always make correct velocity triangles. This will be very helpful for your GATE, ESE, ISRO and BARC examinations and also for your interviews in IITs.

Velocity Triangles for Pumps (in Hindi)

Here we learn about
- pumps with forward backward and radial blades.
- how it effects the efficiency
- which one to use for variable loading
- manometer head
- power of pump

More About Centrifugal Pumps (in Hindi)

Here we learn about
- specefic speed of pumps
- dimensional analysis

Pump Miscellaneous (in Hindi)

Today we are going to study some portions very important for GATE and ESE, we are going to learn about had coefficient, capacity coefficient, power coefficient, auction head coefficient. Selection of pumps, priming of pumps and minimum starting speed for Pumps.

Pump Miscellaneous #2 (in Hindi)

Impact of Jets (in Hindi)
We will study his much force is acted on
1.flat plate
2. Curved symmetric plate
3. Curved vane when jet hits at one end.
All when we have a fixed vane.

Impact of Jets (in Hindi)

Impact of Jets Continued (in Hindi)
We will study his much force is acted on
1.flat plate
2. Curved symmetric plate
3. Curved vane when jet hits at one end.
All when we have a moving vane.

Impact of Jets Continued (in Hindi)

Introduction to Turbines (in Hindi)
Series of vanes, here we will use our understanding of impact of jets and use it to understand working of turbines. Here we learn tangential flow turbines and radial flow turbine.

Introduction to Turbines (in Hindi)

Impulse Turbines (in Hindi). Based on type of energy at inlet of turbine we have 2 types of turbines, reaction turbines and impulse turbines. Here in this lecture we focus on impulse turbines.

Impulse Turbines (in Hindi)

Here we focus on reaction Turbine. We study here Degree of reaction. We'll study about turbine casing, guide vanes, wicket gates, runner, draft tube and turbine governing.

Reaction Turbines (in Hindi)

Degree of reaction will be covered here and we'll know about Francis turbine, hero's turbine and parson's turbine.

Inwards Flow Reaction Turbines (in Hindi)

We will study draft tube, efficiency of draft tube, Kaplan turbine which is very effective under variable loading.

Axial Flow Turbines (in Hindi)

Some miscellaneous topics very important for GATE, ESE and all other PSU examinations, separate research based jobs like BARC, ISRO, DRDO. Here we cover specefic speed and unit speed of turbines and also other unit quantities. We also learn how selection of turbine is done.
