GENERAL INFORMATION

Teaching Staff:

Lecturer, Md Ateeque Khan, JIT ME, atiqfru@gmail.com

Course Web Site: http://abc.jit.edu.in

Class Meetings:

JIT Room 205

Course Objectives:

The objective of fluid machinery is providing basic knowledge about impulse moment and impulse force

that are acting on any Hydraulic turbines. Beside that it also aims on giving various parameters to solve

or calculate the numerical so that it will be convenient in the future for our engineers to apply the best

approach for any design of turbines. The course is intended to provide you with the following benefits:

Applying Concept of Forces that are acting on Hydraulic Machinery.

Different approaches to find power.

What are the various forces that are acting on machinery?

Influence velocity diagram for impulse and reaction turbines.

Influence velocity diagram for centrifugal pumps and reciprocating pumps

Students will interact with live examples used in daily life like irrigation pumps, hand pumps,

pumps by which we wash our vehicle etc.

Students will also learn about the actual function of hydraulics power plant in the fluid machinery

lab.

Study analytical solutions to variety of simplified problems which will help the students to crack

the government sector entrance examination.

Expectations:

This is a 4-unit graduate course. Accordingly, the course has been designed to demand approximately

4 hours per week as per institute time. Two hours per week for practical session scheduled to fill the

gap between theory and practical exposure. It is expected that each student will prepare for and attend

all of the class sessions assignment work will be given which they have to complete with the given

time and class test will be also there which students have to attend regularly. If a student’s fails to do so he will be given zero for that task which is going to reflect a draw down in their Sessional marks.

As per Dr APJ Abdul Kalam Technical University has prescribed that minimum 75% attendance must

be maintain by the students, so I will try my level best to motivate the students for scoring the same.

Academic Integrity:

Full group and class collaboration on all aspects of this course is highly encouraged. It is almost

impossible to share too much information in product development teams but I will try my level best to

give students as much as possible.

Reading Materials:

The primary reading materials for the class are the book Fluid Mechanics and Hydraulic

Machinery by R.K Bansal , and a reading packet. The text is available at the JIT Library, different

booksellers in Barabanki, Lucknow and through internet booksellers.

Grading:

Student’s course grade will be determined as follows:

Class Test=5 (Each Test of 1hour having 5Marks)

Assignment=5(Each Assignment 5Marks)

Sessional Exam=3 (2hour Sessional Exam having 15Marks)

Class Preparation and Participation:

Assignments will be given in the Class after completion of every Unit. Students are expected to come

to class prepared for upcoming topic to understand better and clear your doubts by discussion and

suggested questions. Student’s individual class participation grade will be based upon your in-class

remarks during Sessional marks.

Classes and Topics

Class 1 UNIT-I

Introduction :

We will discuss the introduction part of all 5 units what the topics are and how to learn them and

interconnect them to practical session. We will also discuss the number of practical and how many of

them have to be performed. Read the Journals given in library which will give new ideas to your

subject to link and new projects. In this semester the subject is very important as is linked with other

competitive exams and will be very beneficial for upcoming exams.

Ventuary meter, Pitot tube etc. will be discussed.

Class 4 Saturday, 23Jan

Euler’s fundamental equation

Class 5 , Monday, 25Jan

Introduction to hydrodynamic thrust of jet on a fixed and moving surface (flat plate),

Considering only forces in a horizontal direction u 1 = V and u 2 = 0 therefore

F = QρV = ρAV 2

This will be the thrust on flat plate by the jet of nozzle. This force is responsible to rotate the shaft.

Class 7 Friday, 29 Jan

Introduction to hydrodynamic thrust of jet on a fixed and moving surface (curved plate),

In the x Direction

u 1x = V 1 cos α

u 2x = V v - V r2 cos θ 2 .... ( V r2 = V r1 = V 1 sin α /sin θ 1 ) F x = QρV 1 (cos α + [sin α /sin θ 1 ] cos θ 2 - r > )

r = V v / V 1

In the y Direction u 1y = V 1 sin α

u 2y = V r2 sin θ 2 .... ( V r2 = V r1 = V 1 sin α /sin θ 1 ) In the y direction F y = QρV 1sin α (1 - sin θ 2 / sin θ 1 )

If the vane is moving in the x direction the power developed by the vane P = F x.V V

Class 8, Saturday,30 Jan

Numerical will be solved on discussed topic. The numerical may be taken from the competitive

examination like GATE, IES PSU’S etc.

Class 17 Monday, 15Feb

Degree of reaction, Draft tube, Cavitation in turbines:

Degree of reaction or reaction ratio (R) is defined as the ratio of static pressure drop in the rotor to the

static pressure drop in the stage or as the ratio of static enthalpy drop in the rotor to the static enthalpy

drop in the stage.

Class 18 Tuesday, 16Feb

Principles of similarity, Unit and specific speed:

While Specific Speed refers to the discharge characteristics of a pump, Suction Specific Speed, as the

name implies, refers to the suction characteristics. In should be noted that the values of both of these

terms remain constant for a given pump, regardless of the speed of the pump.

In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge) is

the ratio of the actual discharge to the theoretical discharge, i.e., the ratio of the mass flow rate at the

discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from

the ...
