Pitot Tube
A pitot tube is a small transparent open tube bent at right angle. The basic purpose is to measure the flow i.e. Velocity of the fluid. The point where the velocity of the fluid is zero is known as stagnation point. The pressure at that point is known as stagnation pressure.
p + 1/2 ρ v2 + γ h = constant along a streamline (1)
where
p = static pressure (relative...

Duties of Lubrication Personnel
Following are duties of Lubrication Personnel
Use correct
lubricants in every case and as few types as possible for the plant as a whole.
Apply lubricants
properly.
Apply the correct
amount of lubricant.
Apply lubricants at
proper intervals.
Develop schedules for
items 1 to 4 for each machine, distribute or post them, and see that they are
followed.
Train and instruct
the oilers, and arrange for lubrication clinics if the number of oilers
warrants. Suppliers’ sales and engineering representatives frequently can
render valuable assistance...
Planning Outages
Most companies, as part of their annual business plan, develop
an outage schedule that is based on anticipated business cycle or perceived
maintenance requirements. This outage schedule contains all shutdown dates for
critical production systems. Unfortunately, most of these plans do not consider
the impact on capacity. An effective outage schedule should be configured to
minimize loss of production capacity, product quality and the potential
increase in overall operating cost that can result from poorly coordinated
outage schedules. Care should...

Pro Engineer Installation Steps
For Pro E installation follow the following steps
Start pro/e setup
Open license.dat with any txt-editor and replace every occurance of 00-00-00-00-00-00 with your computer real HOST_D (same one shown in the bottom left corner of the Pro/e setup). Save the license.dat
Save that edited license.dat file , don't replace, remove or delete that file.
Install proe - proe_mech -ptc_distributed_services (optional). On license-config screen select "nodelocked license" and point to edited license.dat
Next apply a patches...

Universal Testing Machine (UTM)
A universal testing machine is used to test the tensile
stress and compressive stress of materials. It is named after the fact that it
can perform many standard tensile and compression tests on materials,
components, and structures. It has the following units
Loading
unit:
In this unit the specimen is clamped and the desired load is applied. It
consist of the following components:

Yield and Ultimate strength
Definition
of Yield strength:
The yield
strength or yield point of a material is defined as the stress at which a
material begins to deform plastically. Prior to the yield point the material
will deform elastically and will return to its original shape when the applied
load is removed.
Importance:
Knowledge of yield point is vital when designing a component
since it generally represents an upper limit of the load that can be applied.
Formula :

FIVE BASIC ELEMENTS OF MPI
SOURCE:-
Source produces
the probing medium or investigating medium. In this MPI test the current is the
source element.
MODIFICATION:
The ability to change or vary the
magnetic field if there is any crack or discontinuity in the specimen. Here in
the MPI test the current is the modifying element.
DETECTION:
The material
which detect that how much change occur in the magnetic field around the
specimen. Here the iron magnetic particle...
Magnetic Particle Testing Inspection
Magnetic
particle testing is accomplished by inducing a magnetic field in a
ferromagnetic material and then dusting the surface with iron particles. The
surface will produce magnetic poles and distort the magnetic field in such a
way that the iron particles are attracted and concentrated making defects on
the surface of the material visible.
How to perform the test:
First put
the specimen into the A.C current carrying coil and then take the specimen into
the beaker. And pour some kerosene oil into the beaker and put some iron powder
in...
Non Destructive Test
Nondestructive testing (NDT) use test
methods to examine an object, material or system without impairing its future
usefulness. Non-destructive testing is often required to verify the quality of
a product or a system. Various types of commonly performed NDT are
1.
Eddy Currents inspection
2. Magnetic Particle Inspection
(MPI or MT)
3.
Radiography
4.
Ultrasonics
5. ...

Evaporator ( In a refrigeration System)
Function of evaporator:
·
In
a refrigeration system, an evaporator is a device which enables a volatile
liquid to vaporize for the purpose of removing heat from a refrigerated space
or product.
·
It
is one of the main components in a refrigeration system.
