I'm just concluding a work in which I had to design a shell and tube exchanger for condensation of a mixture of gases and vapor at low pressure. That was the type I chose.

AEM is a type of shell and tube heat exchanger, according to TEMA standards.

They use 3 letters to describe the configuration of the heat exchanger. First letter refers to the front head, second letter to the shell type and third letter to the rear end stationary head.

So in this case, with a type A you would have:

A for channel and easily removable cover. E as it is a one pass shell and M because you have a fixed tubesheet with a rear end in bonnet shape.

You need to know the torque the motor needs to produce to operate the valve before you can specify the motor. It's all about the amount of power that needs to be delivered to any application that is critical in specifying motors. Motors are rated according to the power needed, so once you have that, then you can select the motor according to rpm and power supply.

ASTM A792 is a standard developed by ASTM International. The full title is ASTM A792/A792M-08 Standard Specification for Steel Sheet, 55% Aluminum-Zinc Alloy-Coated by the Hot-Dip Process. A792 covers 55% aluminum-zinc alloy-coated steel sheets in coils and cut lengths for applications requiring corrosion resistance or heat resistance or both.

yes,up to one year. However the rate again of strength is very slow.

The Standard Method of Measurement known is the SMM7 publish by the the Royal Institution of the Chartered Surveyors is the appropriate method of measurement for building works. The SMM7 rules are simplified enough to produce shorter bill of quantities and the contents updated to conform to modern practice.

Liaison can mean 2 things. It can mean a secret affair, for example: Mary and Ben were having a secret liasison after work Or, it can be when someone/a group of people are working with someone else/a group of other people, for example

Adopting standard-gauge tracks was important for the railroad industry because then railroad cars could be switched from one track to another for more efficient service. The standard size of railroad cards after this action made it possible for railroads to join forces to move products.

The load of a bridge is the amount of weight that can be distributed throughout the bridge without collapsing. Engineers take into effect, wind, rain, and earthquakes when calculating the load.

No, then it would not be a reference dimension. Reference dimensions by definition have no tolerance.

the difference between aircraft maintenance engineer and aeronautical engineer is, aeronautical engineer dose the design work theoritically,while the aircraft engineer maintain and service the airplane

Engineers use blueprints so that they can see what the height and width of a object is going to be and how to make it.

While there is no direct correlation, with higher ferrite numbers ( >30) a factor of 0.7 can be applied to produce % ferrite.

Because it can be melted and melted again

Absolutely! Technical Graphics Communication can be considered a language in the sense that you are able to communicate ideas to other individuals who understand the subtext.

For example an American Civil Engineer can hand a French Civil Engineer a print and both of them would understand the ideas implemented in the drawing even though there is a language barrier.

The same can be considered of mathematics and programming languages.

The amount of money can you save by turning off lights is directly determinant on how many lights you have running, at what power rating and for what amount of time. For instance if you have one light bulb with a 75 watt rating running for 100 hours that will be 75kW-hours (where kW is equal to W x 10^3 or W x 1000) kilo-watt hours are a typical measurement in household meter boxes. If your electricity is being supplied at $0.08/kw-h then it is simply 75 x 0.08 which is equal to $6.00. therefore you can see that, with numerous lights, turning them off can offer a substantial saving over a long period of time, not to mention an important environmental benefit.
