A p. d. of 200<230° V is applied to two branches connected in parallel. The currents in the respective branches are 20<60º A and 40<30º A. Find the apparent power in kV
A) and the active power (in kW) in each branch and in the main network.

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1

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)

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?
