This document discusses HVAC air duct leakage. It begins by defining different types of leakage, including duct leakage, equipment leakage, and system leakage. It explains that duct leakage testing alone does not determine overall system leakage. The document discusses recommendations from codes and standards to test 25% of high-pressure duct. It also addresses questions around how much ductwork should be tested, including low-pressure duct, and why percentage of fan flow is not a suitable metric. The document notes misconceptions around duct leakage testing and provides guidance on good practices for specifications and testing. New tools like SMACNA's duct leakage calculator app are introduced.

This document summarizes research comparing two methods for testing the air barrier in biological safety cabinets: the potassium iodide (KI) discus method and the aerosol liquid method. The research found that the aerosol liquid method provided a more effective and practical test that simulated operator movements and tested across the entire sash, while the KI discus method only tested a localized area. Testing of cabinets using both methods showed that maintaining the proper exhaust fan speed was key to preserving the air barrier and that lowering the main fan speed disrupted the barrier. The research concluded that the aerosol liquid method should be endorsed in Australian standards as a more informative qualitative test of a biological safety cabinet's air barrier performance.

Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.
Supermarket Management System Project Report.pdfKamal Acharya
Supermarket management is a stand-alone J2EE using Eclipse Juno program.
This project contains all the necessary required information about maintaining
the supermarket billing system.
The core idea of this project to minimize the paper work and centralize the
data. Here all the communication is taken in secure manner. That is, in this
application the information will be stored in client itself. For further security the
data base is stored in the back-end oracle and so no intruders can access it.
Open Channel Flow: fluid flow with a free surfaceIndrajeet sahu
Open Channel Flow: This topic focuses on fluid flow with a free surface, such as in rivers, canals, and drainage ditches. Key concepts include the classification of flow types (steady vs. unsteady, uniform vs. non-uniform), hydraulic radius, flow resistance, Manning's equation, critical flow conditions, and energy and momentum principles. It also covers flow measurement techniques, gradually varied flow analysis, and the design of open channels. Understanding these principles is vital for effective water resource management and engineering applications.

Blood finder application project report (1).pdfKamal Acharya
Blood Finder is an emergency time app where a user can search for the blood banks as
well as the registered blood donors around Mumbai. This application also provide an
opportunity for the user of this application to become a registered donor for this user have
to enroll for the donor request from the application itself. If the admin wish to make user
a registered donor, with some of the formalities with the organization it can be done.
Specialization of this application is that the user will not have to register on sign-in for
searching the blood banks and blood donors it can be just done by installing the
application to the mobile.
The purpose of making this application is to save the user’s time for searching blood of
needed blood group during the time of the emergency.
This is an android application developed in Java and XML with the connectivity of
SQLite database. This application will provide most of basic functionality required for an
emergency time application. All the details of Blood banks and Blood donors are stored
in the database i.e. SQLite.
This application allowed the user to get all the information regarding blood banks and
blood donors such as Name, Number, Address, Blood Group, rather than searching it on
the different websites and wasting the precious time. This application is effective and
user friendly.

• Airflow/Volume
– The measurement of the rate of airflow
that passes through a louver,(measured
in cfm/m3s)
• Pressure Drop
– The resistance to airflow across an open
louver (stated in inches of water/kpa)
• Free Area Velocity
– Rate of airflow that passes through the
free area of a louver (expressed in
fpm/ms).
24. Rain Defense
• AMCA 500-L
– The louver test standard
• Water Penetration Test
– The velocity at which .01 ounces of water
passed through the louver
• Wind Driven Rain Test
– New test standard with wind pressure
applied to face of louver
• Effectiveness Class
– New classification of louver performance
25. • Windloads:
– American Society of Civil Engineers
(ASCE) formula
– Hidden or Visible supports
– Effective Wind Speed (mph)
– Louver panel size
• Blade Span (Span tables)
• Intermediate bracing

46. MASTERSPEC - EVALUATIONS
8/93
“Water-penetration testing measures the weight
of water in ounces per sq. ft. of louver free
area passing from the louver’s exterior to the
interior at various air intake velocities...
It is important to realize that the test is based on
still air conditions and simulates the effect of
falling rain and rain flowing down the wetted
surface of a building over a louver…
47. MASTERSPEC - EVALUATIONS
8/93
…While this may provide accurate data
for rain conditions with only fan-induced
air-intake velocities,
no test currently exists that provides
data on louver performance during
exposure to wind driven rain”

56. Louver Rain Defense
• AMCA standard 500-L-99
– AMCA revised its standard to include recommendations
for wind driven rain testing of louvers
• Masterspec 2000
– Includes substantial changes to the advice given when
selecting louvers. Wind driven rain resistant louvers
are now recommended for use.
• Products to meet these needs and
recommendations have been developed
and are increasingly specified.

67. Louver Evolution and Expansion
• “Z” or “J” Non-Drainable Blade Louver
– Good airflow; very little rain defense
• “K” Non-Drainable Blade Louver
– Old “stormproof”; average airflow; very little rain defense
• Drainable Louvers
– Good airflow; some rain defense
• Wind Driven Rain “Storm Resistant” Louvers
– Good airflow on vertical blade; moderate airflow on
horizontal blade; stops most wind driven rain
• “Hurricane” Resistant Louvers –
– Florida Code Compliant Louvers
– Moderate airflow; most stringent tests; severe storm
conditions; missile impact resistance
68. Non-Drainable Louvers

71. Horizontal Line Blade Design
• Most common look
• Adequate blade
support required
• Many blade profiles
for visible or non-
visible lines
• Welded or
mechanically
fastened
• 5’ span for
drainable blades
73. Vertical Line Blade Design
• Becoming more
widely used
• Excellent
mechanical
performance
• Excellent for
Wind Driven
Rain
74. Wind Driven Rain Louver Designs
• Sophisticated
Blade Profiles
• Closely Spaced
• Vertical and
Horizontal Blades
• Increased Depth
• Better Pressure
Drop in many
