If the settling velocity of a particle is 0.30 cm/s and the overflow rate of a horizontal flow clarifier is 0.25 cm/s.

a. what percent of the particles are retained in the clarifier?

b. if the flow rate is doubled, what percent removal of particles would be expected?

c. if a 1.0-m/s flow water treatment plant uses 10 sedimentation basins with an overflow rate of 15 m3/d*m? . what should be the surface area (mº) of each tank?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
