why is it that many universities in the federal have resumeed lectures only federal university of technology owerri haven't, why? please tell me i want to know. or do they think that we are foolish for chosing them as our first and second choice?

Steel which has been rolled out at temperatures below red heat, and then coated with zinc.

Minimum hardness of Mild steel is about 140 Vickers hardness.

The circuit works to put everything together. It can help to integrate all of the system so that you can have all of the things work together.

yes

All of those qualities are relative. Aluminum is a good start. For formed sheet metal, type 5052-H32 is pretty common.

I use .283 lb/in^3 for all steel and stainless alloys. That is close enough for all of them.

to measure the flow in any pipes

It would require (3 X 10)/15 = 2 lb to lift the 3 lb weight. Actually, something a little greater than that. 2 lb is the force to balance it. (Obviously, the lever "has" no force. It requires the force to lift the weight.)

A horizontal beam above a door or a window is commonly refered to as a "lintel."

rod tensile failure

it's very strong

compensation of load by connecting a compensating device which adjust the real and reactive power in the distribution side or load side.

Depends on what pipe you are asking about. Most pipe such as PVC has a max heat rating for internal and external temperatures. this is why regular white PVC should never be used for hot water from a hot water heater which can be 120 degrees (F) or more and melt regular PVC. That is why they recommend using CPVC which has a higher temperature rating. Depends on what pipe you are asking about.

A condensing turbine uses all the energy from the steam going from high pressure turbine to secondary turbine to condensing turbine then sends the condensate back for reheating. where a non condensing turbine just uses the high pressure aspect of the steam then returns the low pressure stream back to be reheated. Condensng turbines utilises the entire available drop from high pressure to the vacuum in the condenser; a back pressure turbine only utilises only the top part, whereas an exhaust steam turbine utilises only th bottom part of the pressure drop. Hope that helps.

A truss is a framework consisting of beams, girders, or rods which lie in a single plane. It is used in large spans and heavy loads, providing a support for bridges and roofs.

Ansi 150 is a pressure grade of flange ie. Ansi #150 Flange. For steel flanges this is specified by ANSI B16.5.

Even with the fantastic analytical tools we have today, almost never is a product developed that has no problems on the first prototype. Something unanticipated always shows up. Also, the experience of doing something really helps, so usually after designing and making a product prototype, ideas for improvements come. It's usually a few cycles before the improvements become so minor they are not worth the next iteration. It can be extremely difficult to know when to stop development on a product.
