What are the responsibilities of a Maintenance Engineer. Please explain into details

What are “Rimmed” and “Killed” steels that an engineer should know? Explain them briefly.

How could we get the chemical element iron (Fe) that is required to make steel? In other words, what are the sources of Fe? Write two sources of Fe that an engineer should know

Traditional method of design and manufacturing is called Sequential Engineering. What would you call the process (__________ Engineering) in which the various teams (design, materials, manufacturing, etc.) work together simultaneously?

A steam Rankine cycle operates between the pressure limits of 1500 psia in the boiler and 1 psia in the condenser. The turbine inlet temperature is 800°F. The turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to produce 2500 kW of power. Calculate the mass flow rate through the boiler, the power produced by the turbine, the rate of heat supply in the boiler, and the thermal efficiency. Use steam tables

What are the advantage and disadvantage of using the advanced technology in the field of engineering.  

An ideal Otto cycle has a compression ratio of 7. At the beginning of the compression process, air is at 98 kPa, 30oC and 766 kJ/kg of heat is transferred to air during the constant-volume heat addition process. Determine (a) the pressure (p3) and temperature (T3) at the end of the heat addition process, (b) the net work output, (c) the thermal efficiency and (d) the mean effective pressure for the cycle. Use the IG model

1) four mechanical solutions principals engage/dimenton of standard disk clutch

2) what is the most essential parameters for designing a flywheel in relation to use their main purpose.

Collect and identify customer needs for international students in any university.

This question is related to product development, so please answer according to that aspect.

Describe in your own words, the term “Dutch Roll”. Discuss how the Dutch roll mode characteristics depend on the static directional stability and lateral stability.

My car is Jeep Cherokee 2016 latitude with two-wheel rear drive, and please give me a complete plan to test my Jeep's suspension system. For the rest information, I can use the values get from Google. Is it underdamped, overdamped, or else? Is it time to replace them yet? Why? If you can provide graph in excel, it would be great, Thanks.

The US consumer fleet (cars, SUV’s, vans, cross-overs and light trucks) has an average drag coefficient of 0.4, an average miles driven per year of 12,500 at 50 MPH and an average frontal area of 5.5 m2. Being that there are 265 million of these ‘average’ vehicles on the road driven by consumers, calculate:

a. Gasoline consumed per vehicle annually assuming 25% overall efficiency

b. Gasoline consumed per vehicle annually assuming if the speed limit on federal highways was cut down from 70 to 55 MPH resulting in a decrease in the average speed to 43 MPH.

c. How many barrels of oil would be saved annually by lowering the speed limit?

d. If instead of 55 MPH there were an absolute federal speed limit on all roads of 45 MPH, lowering the average speed to 35 MPH, repeat b) and c) above.

e. If instead of lowering the speed limit the aerodynamics of all vehicles were improved such that the average vehicle now has a drag coefficient of 0.35, how many barrels of oil would that save annually?

f. If the size of engines were cut down on every vehicle in the fleet equivalent to the efficiency of the average vehicle above increasing to 40%, how many barrels of oil would that save annually?

g. What if by force of tax we were all limited in driving a certain number of miles and this resulted in the original average vehicle driving 10,000 miles per year, how many barrels of oil would that save annually? How many gallons of gas is that per capita and how much would each person save dollar-wise per year?

A cylindrical container with d_o = 0.5 m and L = 7.5 m is used for chemical processing with insulated ends. The inside of the cylinder is kept at 400^o C with 5 kW of power coming from a heater. The outer surface temperature is known to be 78 ^oC and ambient air in the factory is 20C.

a.) Estimate the heat transfer coefficient between the surface of the cylinder and the ambient air and find the thermal resistance between the surface of the cylinder and the chemicals.

A large fan is used to cool the surface of the cylinder with a velocity of 25 m/s. As a result, the heater had to compensate for the cooling in order to maintain the chemicals inside the cylinder at 400C. Assume the air properties are: ? = 0.96 kg/m3, k = 0.032 W/m-K, ? = 215x10-7 Pa-s, and Pr = 0.70.

b.) Estimate the heat transfer coefficient between the air and the cylinder surface.

c.) Estimate the surface temperature of the cylinder after the fan is turned on and determine the increase in the heater power (W).
