Amanometer consists of an inclined glass tube which communicates with a metal cylinder standing upright; liquid fills the apparatus to a fixed zero mark on the tube when both the cylinder and the tube are open to atmosphere. the upper end of the cylinder is then connected to a gas supply at a pressure p and manometer liquid rises through a distance l in the tube. establish the relation;
h=sl [ sin(alpha) + (d/d)^2 ]
for the pressure head h of water column in terms of inclination alpha of the tube, specific gravity s of the fluid, and ratio of diameter d of the to the diameter d of the cylinder.
also determine the value of so that the error disregarding the change in level in the cylinder will not exceed 0.1 percent when = .

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)
