Describe the three primary duties for engineer

What is the mass of a dragster body with a volume of 150 cm3 if it is made of balsa wood?

A desktop computer is to be cooled by a fan whose flow rate is 0.34 m3 / min. Determine the mass flow rate of air through the fan at an elevation of 3400 m where the air density is 0.7 kg/m3.

The interactions between a closed system and its surroundings include energy transfer by heat, boundary work and flow work. a) True b) False

Define a transformation that transforms a square into a rectangle

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.
