Hey, can anyone tell me if Igneous rock is good to build on? Cheers!

What are the characteristics of carbon fibre?

A pressure gage at the inlet to a gas compressor indicates that the gage pressure is 40.0 kPa. Atmospheric pressure is 1.01 bar. The absolute pressure at the exit is 6.5 times the absolute pressure at the inlet.

A cylindrical hot water storage tank (see sketch) for a set of collectors is located in the basement of a dwelling. The tank is made of 0.080" thick steel and insulated with 3" thick fiberglass batt insulation.

The lid on a pressure vessel is held down with 10 bolts that pass through the lid and a flange on the pressure vessel (similar to example 8-4, in the text). The bolts are secured with nuts under the flange. There are no washers.

Both 1042 steel and 4340 steel are used commercially to make quenched round bars of about the same diameter, such as 1 in. Often, these are fully quenched.

The Reynolds number, rhoVD/μ is a very important parameter in fluid mechanics. Determine its value for ethyl alcohol flowing at a velocity of 4 m/s through a 2-in.-diameter pipe.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.

10. Which of these requires a wheel alignment after replacement? A. Struts B. Shocks C. Both
