What mechanism is used to ensure that a pressure-sensitive switch latches into position regardless of the operator speed?

Select one:

O a. Slow-acting mechanism

O b. Spring-loaded mechanism

O c. Momentary-contact mechanism

O d. Over-center mechanism

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)
