1.Water enters and leaves a pump in pipelines of the same diameter and approximately the same elevation. If the pressure on the inlet side of the pump is 30 kPa and a pressure of 500 kPa is desired for the water leaving the pump, what is the head that must be added by the pump, and what is the power delivered to the fluid?
2.The moist unit weight of a soil is 19.kN/m^3. Given that specific gravity is 2.72 and water content is 10.6%, calculate dry unit weight, void ratio, porosity, and degree of saturation.
