2. A small business complex is located 2km down the transmission line, which has series impedance of 0+j0.5 Ω/km. The load voltage of the complex is 480 V rms and the complex consumes 120kW at 0.85 power factor lagging. Determine the voltage and power factor of the source

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)
