pressure = 0.002558 times velocity squared where velocity is miles per hour and pressure is pounds per square foot

for example a wind of 75 mph produces a pressure of

0.002558x75x75 = 14 .39 pounds per square foot

since there are 144 sq in in one sq ft that is 14.39/144 = 0.1 pounds per square inch

In meteorological terms, differences in pressure are what drive wind. Air generally moves toward an area of low pressure. However, due to the rotation of the earth it gets deflected in large scale weather patterns. It is deflected to the right in the northern hemisphere and to the left in the southern hemisphere.

The Engineering department is one of the 6 major operational departments in any 5 star or 5 star deluxe category hotel. It has 3 major functions:

1. Property operations - includes running the utilities like HVAC plant and machinery, water treatment and distribution, boilers and water heating, sewage treatment, external and common area lighting, fountains and water features etc. This is carried out by a dedicated set of personnel working in shifts to cover 24 hours of the day as per a predetermined time schedule. Operations will also include minor trouble shooting and technical support required for guest room snags and banquet setup.

2. Planned Preventive Maintenance (PPM): This is one of the most important functions of Engineering and often cited as the most critical from longtime building asset maintenance point of view. The philosophy is to regularly carry out a set of preventive actions for every machine in the building rather than allow it to run to failure and then tackle expensive breakdown maintenance costs. A PMM schedule is drawn at the beginning of the year and a team of dedicated persons execute it accordingly. In some cases like elevators and kitchen equipments, temporary downtime may be required which is planned in coordination with the affected user departments.

3. Fire and Life safety: Engineering is also responsible to ensure a safe building for its inhabitants. This includes ensuring 100 percent up-time of all the fire pumps serving the sprinkler and hydrants around the building, the Fire Alarm system consisting of smoke detectors, manual call points and alarm bells, egress lights, emergency backup power gensets, inverters, UPS, public address system, CCTV cameras, fire doors, bollards and boom barriers etc. They work hand in hand with security personnel in carrying out evacuation drills and safety checks of the property.

Apart from these lately a new area of focus called Environmental and Energy Management has increasingly taken priority. This includes energy conservation, waste management, recycling and using green measures to reduce the carbon footprint of the building. Some measures would be like replacing incandescent lamps with fluorescent lamps or LEDs, economisers in boilers, heat recovery from AC condenser water etc.

The Engineering expenses including the energy cost and repairs and maintenance expenses accounts anywhere between 10 to 18 percent of the revenue depending on size and external environmental factors of the building. This lays added emphasis for accurate budgeting and efficient spares and consumable inventory management. Chief Engineers (or Director Engineering in larger hotels) would spend most of their time planning, budgeting or doing complain analysis to figure out medium and long term solutions for the hotel's technical challenges.

Explain the decision support system concept and how it differ from traditional management information system?

===============================================================

Difference Between DSS and MIS:-

MIS:

1) Management Information system operates on operational efficiency i.e. it concentrates to do the things in right manner.

2) It allows the communication across the managers from different areas in a business organisation.

3)It allows flow of information in both upward and downward direction.

4)MIS is original form of management information.

DSS:

1) Decision support system helps in making effective decisions as it allows to do only right things.

2) It is concerned about leadership and senior management in an organization providing effective judgment support.

3)It flows only in upward direction.

4)DSS is actually advancement of MIS.

27 megahertz is a rate of 27 million cycles every second. Usually any form of RF-controlled device, such as RC cars use a wide variety of different frequencies to prevent interference. Take for example, most cordless phones nowadays operate on a 2.4GHz band (where previous ones used 900MHz roughly before 2004) which competes with devices that are compliant with every IEEE wireless networking standard up to 802.11ac (which operates on a 5GHz band).

In engineering terms, dead load refers to the unchanging weight of a structure itself, plus any other load that may permanently be a part of the structure. On a bridge, for example, the main dead load would be the weight of bridge, and there would also be the weight of the abutments and perhaps a tollbooth.

Software products are two types, they are (1) Problem Domain solutions, currently most of the companies, currently trying to convert their projects into products with the help of their existing requirements. In this context they do have their own proprietory frameworks, common utils and (2) Tool software, these kind of products are used in different phases of SDLC.

1 inch = 2.54 centimeters or 25.4 millimeters

A simple manual wire stripper is a pair of opposing blades much like scissors or wire cutters. The addition of a center notch makes it easier to cut the insulation without cutting the wire. This type of wire stripper is used by rotating it around the insulation while applying pressure in order to make a cut around the insulation. Since the insulation is not bonded to the wire, it then pulls easily off the end. This is the most versatile type of wire stripper.

Another type of manual wire stripper is very similar to the simple design previously mentioned, except this type has several notches of varying size. This allows the user to match the notch size to the wire size, thereby eliminating the need for twisting. Once the device is clamped on, the remainder of the wire can simply be pulled out, leaving the insulation behind.

Engineering is maths.

Every branch of Engineering (Chemical, Process, Stationary, Mechanical, Electrical etc.) is based in the application of math to the physical world to describe the transfer of heat, energy, mass and momentum. Math details the impact of stress, strain, erosive chemicals and heat on systems. Math is used in risk management, cost estimation, life span calculations, scale up and downsizing.

Venturimeter is the short pipe having two conical parts and portion of uniform cross section between these two parts.

reflect light well-normally shinysmooth pale colour objects: mirror, glass, shiny metal, tin foil...these objects favour a good image due to the reflection of light is regular do not reflect light well-usually rough, matt , dark colured objects: tree trunk, car wheel, dark carboard, brick, stone, dark opaque plastic... These objects diffuse the picture or do not giva a picture at all because reflected light is irregular.

It is possible to network several computers using a wireless connection in a workgroup. However, a workgroup has disadvantages such as setting up accounts each with a password, takes time to setup, not easy to expand and file sharing has a maximum limit.

a lens will refract light. a mirror will reflect the light.

Use of the engineering process

Alternating current is much more efficient to transmit than direct current. Using transformers, it can be stepped up to high voltages for transmission over long distances using relatively small conductors, and then stepped down at the destination to provide high current.

I don't use engineering drawings.... I guess?!
