QUESTION 1
a) Two resistances of 812 and 1222 are connected in parallel. These resistances further connected in
series with a 5.212 resistance. If current through the 5.292 resistance is 1.2 amperes, what will be
the current through the 812 and 12 respectively, the total resistance of the circuit and voltage
across the whole circuit?

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)
