Mechanical Engineering

Mechanical engineers design, build, and maintain a variety of systems, primarily focusing on thermal systems and mechanical systems. Thermal systems include heating, ventilation, and air conditioning (HVAC) systems, as well as engines and refrigeration units. Mechanical systems encompass machinery, robotics, and manufacturing equipment. Both types of systems are crucial for industrial processes, energy efficiency, and overall functionality in various applications.

A marine technician that works for marine dealerships earn an average of about $35,960 a year, so about $2,299,67 a month. Marine technicians that work in the ship and boat building earned about $40,550 a year, about $3,379.20 a month. Those work on coastal states (Alaska, Massachusetts, New Jersey, California, Connecticut, Maryland, etc.) usually earn more than others that don't.

No, it is relatively low compared to steel; aluminumdensity is 2.7 g/cc (.098 lb per cu in) while steel is 3 times higher

A bachelor's degree in most areas can require between 124 to 128 college credits particular to a specific program of study. This would be based on a college or university that operates on a regular two semester academic year which is the most common. For institutions that operate on a tri-semester or quarter-semester it would be quite different. That being said, the Bachelor's degree - in most cases - is designed as a four year program of study, provided the student is full-time and follows their chosen program of study as prescribed by the college or university, and also provided the individual does not require prerequisite or developmental coursework as a result of basic skills testing. The minimum credit load for a full-time student is no less than 12 credits per semester. However, to complete the degree within the four years, a credit load of approximately 15 to 18 credits is recommended. For individuals who work or who have other responsibilities that would prohibit them from attending full-time, completion of the degree may take twice as long. Still, some of this time can be cut down by attending summer sessions and/or interim sessions. In addition, the bachelors and associate degrees are referred to as undergraduate degrees while the masters and doctorate degrees referred to as graduate degrees.

thermodynamics, is essential for mechanical engineers, because the subject is mainly about heat and work in system, and as an engineer that is important, especially when you have to design engines, because that is when you have to determine important factors such as the amount of work that can be done by that engine internally, and the heat it transefered and obtained.

I'm guessing you're talking about a disc viscometer, in which case the higher the viscosity, the higher the measured torque.

advantages of a globe valve

* you get instant access to the supply: only a 90 degree turn to open fully * less maintenance is required to the valve as you won't have to re-seat it disadvantage of a globe valve

* it is harder to finely adjust the flow of your substance compared to a gate valve: a gate valve requires many more turns to fully open and close than the single 90o "part-turn" required on a globe valve

with out mechanical engineering the world is a big zero. no products in the world is created artificially with out the application of mechanical engg. that's y i have studied mech engg.

Nobody knows. There were gears thousands of years ago.

First of all

frp full form is glass reinforce plastic and

grp full form is glass reinforce polyester

the difference between this two is,grp is one of the type of frp pipes

like other types are grv (glass reinforce venylester)and gre (glass reinforce epoxy) depends on type of resin(chemical) to be used to make frp pipe.

Metal gauge is inversely proportional to thickness, the bigger the thickness lesser the gauge.

Following is conversion table:-

10 G : 3.15 MM

11 G : 2.8 MM

12 G : 2.5 MM etc....

A pitot tube is used to measure local velocity in a flowing fluid. The pitot tube

hole must face the flowing fluid. The local velocity, u , is given by :

u = SQRT [ ( delta P ) ( 2 ) ( g sub C ) / ( rho ) ]

mainly two types of Vibration measurement: shaft vibration Bearing Vibration

If the hoses ("tubes") expand, the pressure available at the working device will be lower, reducing the force available. Also, if the hoses are moving around because they are flexible, they are more likely to get worn or damaged.

There is not a straight forward answer to this question. Basically the strengths of mild steels depends on its material composition. All steels are made with varying alloys and are made from different processes eg. casting, hot or cold rolling and they all have a different effect on its strength. If you know the specifications of the mild steel you are using there are tables for which you can obtain these values. Typically I have seen the yield stress vary from 250 MPa to as much as 550MPa, so you can have an idea of just how much they vary based on their composition.

Many civil engineers work for consulting firms. Their clients are often city governments who need help with their sewers and water systems. Companies hire them to deal with air polution as well as water and sewage problems. They work for architects and plan the technical details of construction. Some work as expert witnesses for lawyers. They design bridges and highways for all levels of government.

The difference is that geysers are way much hotter than the steam from hot springs. The geysers can give you 3rd degree burns. But so can the steam from hot springs if you're in there to long.
