Apower cycle operating at steady state receives energy by heat transfer at a rate at 1800 k and rejects energy by heat transfer to a cold reservoir at a rate at 600 k. for each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, or is impossible. a. q._h = 500 kw, q._c = 100 kw b. q._h = 500 kw, w._cycle = 250 kw, q._c = 200 kwc. w_cycle = 350 kw, q._c = 150 kw d. q._h = 500 kw, q._c = 200 kw.

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa. s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)

A)-explain briefly the importance of standards in engineering design. b)- what is patent? c)-explain the relationship between these standards: b. s. and b. s.en d)- in engineering design concepts, types of loads and how they act are important factors. explain.
